The testing of unsaturated soils requires greater care and effort than that of saturated soils. Although unsaturated soil mechanics has been embraced by geotechnical engineering, engineering practice has not yet caught up as the characterization of unsaturated soils is difficult and time-consuming, and made harder still by a lack of standards. Laboratory Tests for Unsaturated Soils collates test procedures to cover all laboratory tests for characterising unsaturated soils. It covers the background, theory, test procedures, and interpretation of test results. Each test procedure is broken down into simple stages and described in detail. The pitfalls of each test and the interpretation of the test results are explained. Test data and calculation methods are given, along with many numerical examples to illustrate the methods of interpretation and to offer the presentation of typical results. The book is especially useful for students and researchers who are new to the field and provides a practical handbook for engineering applications.

This accessible, clear and concise textbook strikes a balance between theory and practical applications for an introductory course in soil mechanics for undergraduates in civil engineering, construction, mining and geological engineering. Soil Mechanics Fundamentals lays a solid foundation on key principles of soil mechanics for application in later engineering courses as well as in engineering practice. With this textbook, students will learn how to conduct a site investigation, acquire an understanding of the physical and mechanical properties of soils and methods of determining them, and apply the knowledge gained to analyse and design earthworks, simple foundations, retaining walls and slopes. The author discusses and demonstrates contemporary ideas and methods of interpreting the physical and mechanical properties of soils for both fundamental knowledge and for practical applications. The chapter presentation and content is informed by modern theories of how students learn: *Learning objectives inform students what knowledge and skills they are expected to gain from the chapter. *Definitions of Key Terms are given which students may not have encountered previously, or may have been understood in a different context. *Key Point summaries throughout emphasize the most important points in the material just read. *Practical Examples give students an opportunity to see how the prior and current principles are integrated to solve real world problems.

Rock Dynamics - Experiments, Theories and Applications is a collection of scientific and technical papers presented at the Third International Conference on Rock Dynamics and Applications (RocDyn-3, Trondheim, Norway, 26-27 June 2018). The papers in the book reflect the recent developments in experiment and theory as well as engineering applications of rock dynamics. Rock dynamics studies the response of rock and rock masses under dynamic loading and during the state transition from static loading to kinetic movement. It also includes the study of engineering countermeasures to dynamic instability of rock and rock masses. The topics in the book include: - Dynamic theories - Numerical simulation - Propagation of stress waves - Dynamic tests of rock - Stability of underground openings under dynamic loading - Rockburst - Seismic monitoring - Dynamic rock support - Blasting - Earthquake-related rock structure damage, etc. Applications, such as rockburst, dynamic rock support, seismic monitoring, blasting and earthquake-related rock structure damage, are paid special attention in Rock Dynamics - Experiments, Theories and Applications. The papers, from specialists both from mining and tunnelling branches, discuss commonly interested dynamic issues. Their experience and knowledge in the application of rock dynamics are extremely valuable for all academics, engineers and professionals who work with rock dynamics.

Rock Mechanics and Engineering Geology in Volcanic Fields includes keynote lectures and papers from the 5th International Workshop on Rock Mechanics and Engineering Geology in Volcanic Fields (RMEGV2021, Fukuoka, Japan, 9-10 September 2021). This book deals with challenging studies related to solving engineering issues around volcanic fields, including: Volcanic geology, disasters and their mitigation Resources and energy in volcanic fields Mechanical behavior of volcanic rocks and soils Groundwater and environmental problems in volcanic fields Geotechnical engineering in volcanic fields Rock Mechanics and Engineering Geology in Volcanic Fields is of great interest to civil engineers and engineering geologists working in the areas of rock and soil mechanics, geotechnical engineering, geothermal energy, engineering geology, and environmental science.

At some time 30% of the world's land mass was covered by glaciers leaving substantial deposits of glacial soils under major conurbations in Europe, North and South America, New Zealand, Europe and Russia. For instance, 60% of the UK has been affected, leaving significant glacial deposits under major conurbations where two thirds of the population live. Glacial soils are composite soils with significant variations in composition and properties and are recognised as challenging soils to deal with. Understanding the environment in which they were formed and how this affects their behaviour are critical because they do not always conform to classic theories of soil mechanics. This book is aimed at designers and contractors working in the construction and extractive industries to help them mitigate construction hazards on, with or in glacial deposits. These soils increase risks to critical infrastructure which, in the UK includes the majority of the road and rail network, coastal defences such as the fastest eroding coastline in Europe and most of the water supply reservoirs. It brings together many years of experience of research into the behaviour of glacial deposits drawing upon published and unpublished case studies from industry. It draws on recent developments in understanding of the geological processes and the impact they have upon the engineering properties, construction processes and performance of geotechnical structures. Unlike other books on glaciation it brings together all the relevant disciplines in earth sciences and engineering to make it directly relevant to the construction industry.

Soil nailing is an in situ soil reinforcement technique that can be used to enhance the stability of slopes, retaining walls, embankments, and excavations. It involves installation of closely spaced, relatively slender unstressed tension-carrying structural elements into the ground to stabilize the soil mass. These elements, which are called soil nails, comprise steel or other engineering materials such as fiber reinforced polymer. Soil nailing did not gain popularity until the 1970s when engineers started to realize that the technique could offer an effective, robust, and economical reinforcing system for a variety of ground conditions. More importantly, the track record has been excellent in that no major collapses have been reported in properly designed and well-constructed soil nailed structures so far. Considerable experience and knowledge of the technique have been gained in the past few decades through systematic technical development work comprising laboratory tests, numerical modeling, physical modeling, site trials and field monitoring covering design, and construction practices. Soil Nailing: A Practical Guide consolidates the experience and advances made in the development and use of the soil nailing technique and encourages a wider adoption of the technique by practitioners. The book is intended for use by postgraduate students, researchers, and practicing civil and geotechnical engineers, who wish to have a more in-depth and fundamental understanding of the theory and practice behind the technique. It presents the basic principles of the technique as well as state-of-the-art knowledge and recommended standard of good practice in respect of design, construction, monitoring, and maintenance of soil nailed structures.

Tajikistan is one of the lesser-known and least-researched former Soviet Central Asian republics. The birth of the new state in 1991 was followed closely by a civil war which killed more than 50,000 people and displaced many tens of thousands more. While a peace agreement was signed in 1997, significant political violence continued until 2001 and intermittent outbreaks still occur today. Many claim it remains a very weak state and perhaps in danger of state failure or a return to civil war. However, the revival of Tajikistan should not simply be seen in terms of its post-conflict stabilization. Since its creation as a republic of the Soviet Union in 1920s, Tajikistan has been transformed from being a shell for socialist engineering to become a national society under a modern state. Despite a multitude of economic, social and political shocks, the Republic of Tajikistan endures. This book places the transformation of Tajikistan in its Soviet and Post-Soviet historical settings and local and global contexts. It explores the sources of a state with Soviet roots but which has been radically transformed by independence and its exposure to global politics and economics. The authors address the sources of statehood in history, Islam and secularism, gender relations, the economy, international politics and security affairs. This book is a new edition of a special issue of Central Asian Survey, 'Tajikistan: the sources of statehood', including two additional papers and a revised introduction.

This book is an introduction to numerical analysis in geomechanics and is intended for advanced undergraduate and beginning graduate study of the mechanics of porous, jointed rocks and soils. Although familiarity with the concepts of stress, strain and so on is assumed, a review of the fundamentals of solid mechanics including concepts of physical laws, kinematics and material laws is presented in an appendix. Emphasis is on the popular finite element method but brief explanations of the boundary element method, the distinct element method (also known as the discrete element method) and discontinuous deformation analysis are included. Familiarity with a computer programming language such as Fortran, C++ or Python is not required, although programming excerpts in Fortran are presented at the end of some chapters. This work begins with an intuitive approach to interpolation over a triangular element and thus avoids making the simple complex by not doing energy minimization via a calculus of variations approach so often found in reference books on the finite element method. The presentation then proceeds to a principal of virtual work via the well-known divergence theorem to obtain element equilibrium and then global equilibrium, both expressed as stiffness equations relating force to displacement. Solution methods for the finite element approach including elimination and iteration methods are discussed. Hydro-mechanical coupling is described and extension of the finite element method to accommodate fluid flow in porous geological media is made. Example problems illustrate important concepts throughout the text. Additional problems for a 15-week course of study are presented in an appendix; solutions are given in another appendix.

The dissolution of the communist system led to the creation of new states and the formation of new concepts of citizenship in the post-Soviet states of Central and Eastern Europe. The formation of national identity also occurred in the context of the process of increasing economic and political globalisation, particularly the widening of the European Union to include the central European post-socialist and Baltic States. Internationally, Russia sought to establish a new identity either as a European or as a Eurasian society and had to accommodate the interests of a wider Russian Diaspora in the 'near abroad'. This book addresses how domestic elites (regional, political and economic) influenced the formation of national identities and the ways in which citizenship has been defined. A second component considers the external dimensions: the ways in which foreign elites influenced either directly or indirectly the concept of identity and the interaction with internal elites. The essays consider the role of the European Union in attempting to form a European identity. Moreover, the growing internationalisation of economies (privatisation, monetary harmonisation, dependence on trade) also had effects on the kind of 'national identity' sought by the new nation states as well as the defining by them of 'the other'. The collection focuses on the interrelations between social identity, state and citizenship formation, and the role of elites in defining the content of concepts in different post-communist societies. This book was originally published as a special issue of Europe-Asia Studies.

Steve Hencher presents a broad and fresh view on the importance of engineering geology to civil engineering projects.

Practical Engineering Geology provides an introduction to the way that projects are managed, designed and constructed and the ways that the engineering geologist can contribute to cost-effective and safe project achievement. The need for a holistic view of geological materials, from soil to rock, and of geological history is emphasised. Chapters address key aspects of

• Geology for engineering and ground modelling
• Site investigation and testing of geological materials
• Geotechnical parameters
• Design of slopes, tunnels, foundations and other engineering structures
• Identifying hazards
• Avoiding unexpected ground conditions

The book is illustrated throughout with case examples and should prove useful to practising engineering geologists and geotechnical engineers and to MSc level students of engineering geology and other geotechnical subjects.

Problems in nonlinear structural dynamics and critical excitation with elastic-plastic structures are typically addressed using time-history response analysis, which requires multiple repetitions and advanced computing. This alternative approach transforms ground motion into impulses and takes an energy balance approach. This book is accessible to undergraduates, being based on the energy balance law and the concepts of kinetic and strain energies, and it can be used by practitioners for building and structural design. This presentation starts with simple models that explain the essential features and extends in a step-by-step manner to more complicated models and phenomena.

Natural soft soils are very complex materials. As construction activities increasingly take place in poor ground conditions, ground improvement is often required. However, design practices for ground improvement were for long at best crude and conservative, and at worst unsafe. Although new construction and field observation techniques have been developed to ensure that geotechnical structures such as embankments, tunnels and deep excavations can be built safely under these difficult conditions, design is still predominantly based on empirical rules and simplifying assumptions.

Since 2000 increased computer power has made systematic numerical studies utilising the 3D finite element method more and more possible. This enabled the investigation of complex soil-structure interaction mechanisms associated with ground improvement problems. The EC-funded Research Training Network Soft Clay Modelling for Engineering Practice (SCMEP), was set up to develop improved constitutive and numerical models to assist in geotechnical design on soft clays, and made significant advances in theory backed up with substantial experimental programmes (2000-2004). The EC-funded Marie Curie Research Training Network AMGISS (Advanced Modelling of Ground Improvement on Soft Soils) continued the research by the SCMEP network, focussing on modelling ground improvement systems. The aim of the AMGISS network is to develop advanced numerical modelling techniques for analysing the coupled hydro-mechanical behaviour of ground improvement systems on soft soils utilising advanced constitutive modelling, physical modelling and 2D, enhanced 2D and 3D numerical modelling techniques.

The motivation of the 2nd International Workshop on Geotechnics of Soft Soils, organised by the AMGISS network (3-5 September 2008, Glasgow, Scotland), was to bring together practitioners and academics to discuss recent developments in soft soil modelling, focussing on ground improvement. This volume is a collection of papers from the workshop, and discusses the state-of-the-art in soft soil modelling and design, with particular emphasis on ground improvement applications, involving contibutions both from academia and industry. The topics included cover: Modelling (constitutive modelling, numerical modelling, and physical modelling), Design and Application (focusing mainly on embankments and foundations), and Ground Improvement (preloading and consolidation methods, column methods, piles and micropiles, and other ground improvement methods).

Geotechnics of Soft Soils - Focus on Ground Improvement will prove to be invaluable to research students, academics and practitioners, working in geotechnical design on soft soils.

Design and Construction of Pavements and Rail Tracks - Geotechnical Aspects and Processed Materials is a compilation of selected contributions produced between 2002 and 2005 by the International Committee TC3 - Geotechnics of Pavements of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE), a committee dedicated to gathering current knowledge of geotechnical aspects relating to pavements and rail tracks. The volume presents advanced procedures for laboratory and field materials characterization, including processed materials (non-conventional road construction materials), novel tests for field stiffness evaluation, a pre-standard for roller integrated continuous compaction control and new theories for evaluation of the long term performance of materials, including environmental aspects. These contributions represent the latest developments relating to the design, construction and long term performance of pavements, rail tracks and earth structures, with emphasis on the geotechnical and environmental background.

A logical, integrated and comprehensive coverage of both introductory and advanced topics in soil mechanics in an easy-to-understand style. Emphasis is placed on presenting fundamental behaviour before more advanced topics are introduced. The use of S.I. units throughout, and frequent references to current international codes of practice and refereed research papers, make the contents universally applicable. Written with the university student in mind and packed full of pedagogical features, this book provides an integrated and comprehensive coverage of both introductory and advanced topics in soil mechanics. It includes: worked examples to elucidate the technical content and facilitate self-learning a convenient structure (the book is divided into sections), enabling it to be used throughout second, third and fourth year undergraduate courses universally applicable contents through the use of SI units throughout, frequent references to current international codes of practice and refereed research papers new and advanced topics that extend beyond those in standard undergraduate courses. The perfect textbook for a range of courses on soils mechanics and also a very valuable resource for practising professional engineers.

Modelling forms an implicit part of all engineering design but many engineers engage in modelling without consciously considering the nature, validity and consequences of the supporting assumptions. Derived from courses given to postgraduate and final year undergraduate MEng students, this book presents some of the models that form a part of the typical undergraduate geotechnical curriculum and describes some of the aspects of soil behaviour which contribute to the challenge of geotechnical modelling. Assuming a familiarity with basic soil mechanics and traditional methods of geotechnical design, this book is a valuable tool for students of geotechnical and structural and civil engineering as well as also being useful to practising engineers involved in the specification of numerical or physical geotechnical modelling.

This publication contains three special lectures, six keynote addresses and sixty-eight technical papers presented at the symposium. The wide variety of topics covered are grouped in the proceedings according to subject.

This book contains a sampling of papers presented at the June 2-5, 2002 International Workshop on Bifurcations andamp; Instabilities in Geomechanics (IWBI 2002). The scope of the Workshop includes analytical approaches, numerical methods, and experimental techniques.

Although primarily designed as a supplement to Soil Mechanics: Basic Concepts and Engineering Applications, this book can be used as anindependent problem solving text, since there is no specific reference to any equation or figure in the main book and contains problems and fully-worked solutions. Written for university students taking first-degree courses in civil engineering, environmental and agricultural engineering, its main aim is to simulate problem solving learning as well as facilitating self-teaching. The special structure of the book makes it possible to be used in two, three and four year undergraduate courses in soil mechanics. As it includes new and advanced topics tis work book will also be a valuable resource for the practising professional engineer. Although readers are assumed to have prior knowledge in soil mechanics; necessary basic information is included in each worked example.
