This text, based on an international symposium held in 1994, covers geosynthetic clay liners (GCL), a type of geosynthetic material which blends natural soil and geosynthetics in the form of a composite barrier-system. Environmental applications have been a major use of GCL.

This handbook provides an introduction to the application possibilities of geosynthetics as building material, covering soil structures, foundations engineering and bank and bed protection. The text covers general design considerations and elaborated examples.

The development of centrifuge technology presents geotechnical engineers with a very powerful and sophisticated technique for investigating geotechnical problems. The centrifuge can make significant contributions to understanding the mechanics of geotechnical materials and to the development of new analytical methods, and is widely accepted as an excellent technique for modelling specific situations. With the range of machinery and ancillary equomnt avaiwe and the increasing expertise of the engineering community, the centrifuge test has become a very important tool for sowing many geotechnical engineering problems. In this book, a team of practitioners provides a comprehensive overview of centrifuge testing. Starting from first principles and practical considerations, the book then discusses applications of the test in modelling such geotechnical structures and processes as foundations and retaining walls, environmental geomechanics and cold regions engineering. Professional and academic geotechnical, civil and structural engineers should find this a compact and thorough discussion of centrifuge testing.

Discussing rock breakage by blasting, this text includes: results of complex investigations into the rock breakage mechanism and the patterns of crack formation during a blast; problems of modelling; and principal equations linking the model with prototype and similarity criteria.

The major problems in predicting soil-structure interaction are based on the fact that soil is neither homogeneous nor elastic and is invariably much weaker than the structure it has to support. This text describes how a number of different methods of analysis and modelling, including the boundary element method, the finite element method and a range of classical methods, are used to answer some of the questions associated with soil-structure interaction. Contributions from 19 international practising engineers and researchers cover the following main topics: caverns; dams; embankments; excavations; subsidence; pavements; piles; pipelines; retaining walls and tunnels.

The results of theoretical and experimental investigations of seismic waves depending on natural and technological factors are discussed, with methods for engineering calculations of industrial blast parameters.

The stability of underground and surface geotechnical structures during and after excavation is of great concern as any kind of instability may result in damage to the environment as well as time-consuming high cost repair work. The forms of instability, their mechanisms and the conditions associated with them must be understood so that correct stabilisation of the structure through rock reinforcement and/or rock support can be undertaken. Rock Reinforcement and Rock Support elucidates the reinforcement functions of rock bolts/rock anchors and support systems consisting of shotcrete, steel ribs and concrete liners and evaluates their reinforcement and supporting effects both qualitatively and quantitatively. It draws on the research activities and practices carried out by the author for more than three decades and has culminated in a most extensive up-to-date and a complete treatise on rock reinforcement and rock support.

The first comprehensive treatment of the subject of design methodology in rock engineering, this book emphasizes that a good designer needs not only knowledge for designing (technical knowledge) but also must have knowledge about designing (an appropriate process to follow). Design methodology is today recognized in most fields as crucial to the success of a new product, process, or construction project. This unique book starts with an appraisal of current trends concerning global design activities and competitiveness and gives an insight into how designers design. The state of the art in engineering design is given with a detailed expose of all significant design theories and methodologies. It then presents a design methodology specifically for rock engineering and demonstrates its practical use on the basis of important case histories. To preserve the momentum of the design message, design education is also discussed. A separate chapter is devoted to skills development, presenting the designer with an extensive repertoire of widely available tools and concepts. The Appendix lists a compendium of useful design charts for rock engineering, traced after a thorough literature search. A Bibliography concludes the book with an up-to-date list of references.

The world requires an increasing number of underground facilities for applications such as storage, waste repositories and traffic. Accurate prediction of the stability and deformation of these facilities is essential, and calls for model calculations using reliable and comprehensive constitutive equations describing the mechanical behaviour of the rocks involved, particularly the time-dependent effects. Here the authors combine their knowledge and personal experience in this field to encourage the practical use of material laws based on a sound physical and mathematical basis. Further discussion and research on the time-dependent behaviour of rocks and related materials is supported in the text by more than 200 figures. The text covers elasticity, creep, dilatancy, creep failure and short term failure, experimental techniques and test results, micromechanical deformation mechanisms, viscoplasticity and computation using appropriate constitutive equations, including many fundamental model calculations. Rock mechanics incorporates aspects of many disciplines including structural geology, soil mechanics, material sciences, civil, mining and petroleum engineering, seismology and geophysics. This book will therefore find a wide appreciation amongst engineers, researchers and graduate students in these and other related areas.

The papers compiled in this book cover almost all aspects of in-situ characterization ranging from rock mass classification measurement of in-situ stresses, strength and deformation characteristics to field instrumentation and back analysis of observations made.

An introduction to the investigation, extraction, processing and specification of natural soil and rock materials, with an emphasis on why particular material properties are sought and how they may be modified. The book covers the full range of soil and rock construction materials including crushed stone, sand and gravel, natural and prepared roadbase, earth fill and rock fill, heavy clays, armour stone and dimension stone. Environmental aspects of quarrying, such as the use of waste materials, blast monitoring and pit reclamation, are studied in detail. New developments are discussed such as the trend towards fewer but larger quarries, the employment of by-products, and the need for upgrading marginal materials. The use of plenty of diagrams and photos, and a clear writing style, make this an easy book to follow and extensive reference lists in each chapter guide the reader further into the more specialist topics.

Translated from the second Russian edition of 1988. Parts 2, "Soil mechanics" and 3, "Foundations and footings" are revised and updated versions of the first Russian edition of 1981. Part 1, "Special course in engineering geology," contains a discussion of physicomechanical properties of soil, geody

The design of structures in general, and prestressed concrete structures in particular, requires considerably more information than is contained in building codes. A sound understanding of structural behaviour at all stages of loading is essential. This textbook presents a detailed description and explanation of the behaviour of prestressed concrete members and structures, both at service loads and at ultimate loads, and in doing so, provides a comprehensive and up-to-date guide to structural design. Much of the text is based on first principles and relies only on the principles of mechanics and the properties of concrete and steel, with numerous worked examples. However, where the design requirements are code specific, this book refers to the provisions of the Australian Standard for Concrete Structures (AS3600-2009) and, where possible, the notation is the same as in AS3600-2009. A parallel volume is written to Eurocode 2, the European Standard for the Design of Concrete Structures. The text runs from an introduction to the fundamentals to in-depth treatments of more advanced topics in modern prestressed concrete structures. It suits senior undergraduate and graduate students, and also practising engineers who want a comprehensive guide to the design of prestressed concrete structures. It retains the clear and concise explanations and the easy-to-read style of the first edition, but the content has been extensively reorganised and considerably expanded and updated. New chapters cover design procedures, actions, and loads; prestressing systems and construction requirements; and connections and detailing. The topic of serviceability is developed extensively throughout. The authors have been researching and teaching the behaviour and design of prestressed concrete structures for more than 35 years, and this updated edition of the book reflects this wealth of experience. The work has also gained much from Ian Gilbe.

Rock Slope Engineering covers the investigation, design, excavation and remediation of man-made rock cuts and natural slopes, primarily for civil engineering applications. It presents design information on structural geology, shear strength of rock and ground water, including weathered rock. Slope design methods are discussed for planar, wedge, circular and toppling failures, including seismic design and numerical analysis. Information is also provided on blasting, slope stabilization, movement monitoring and civil engineering applications. This fifth edition has been extensively up-dated, with new chapters on weathered rock, including shear strength in relation to weathering grades, and seismic design of rock slopes for pseudo-static stability and Newmark displacement. It now includes the use of remote sensing techniques such as LiDAR to monitor slope movement and collect structural geology data. The chapter on numerical analysis has been revised with emphasis on civil applications. The book is written for practitioners working in the fields of transportation, energy and industrial development, and undergraduate and graduate level courses in geological engineering.

Bridges the Gap between Geology and Ground Engineering High-quality geological models are crucial for ground engineering projects, but many engineers are not always at ease with the geological terminology and analysis presented in these models, nor with their implications and limitations. Project engineers need to have a sound comprehension of the geological models presented to them, and to be able to discuss the models in so far as they might impinge on the design, safety and possible budgetary or time constraints of the project. They should also fully understand how site investigation data and samples are used to develop and substantiate geological models. Geology for Ground Engineering Projects provides a comprehensive presentation of, and insight into, the critical geological phenomena that may be encountered in many engineering projects, for example rock contact relationships, weathering and karst phenomena in tropical areas, composition of fault zones and variability of rock discontinuities. Examples are provided from around the world, including Southeast Asia, Europe, North and South America, China and India. Comprehensive and well-illustrated, this definitive book: Describes the important geological phenomena that could affect ground engineering projects Provides a practical knowledge-base for relevant geological processes Addresses common geological issues and concerns Rocks are described in relation to the environment of their formation, highlighting the variation in composition, distribution and geotechnical properties that can be expected within a variety of rock associations. Case studies, where geology has been a vital factor, are included. These are written by the project engineers or geologists responsible for the projects. Geology for Ground Engineering Projects is well illus

An Ideal Source for Geologists and Others with Little Background in Engineering or Mechanics Practical Rock Mechanics provides an introduction for graduate students as well as a reference guide for practicing engineering geologists and geotechnical engineers. The book considers fundamental geological processes that give rise to the nature of rock masses and control their mechanical behavior. Stresses in the earth's crust are discussed and methods of measurement and prediction explained. Ways to investigate, describe, test, and characterize rocks in the laboratory and at project scale are reviewed. The application of rock mechanics principles to the design of engineering structures including tunnels, foundations, and slopes is addressed. The book is illustrated throughout with simple figures and photographs, and important concepts are illustrated by modern case examples. Mathematical equations are kept to the minimum necessary and are explained fully the book leans towards practice rather than theory. This text: Addresses the principles of rock mechanics as it applies to both structural geology and engineering practice Demonstrates the importance of and methods of geological characterisation to rock engineering Examines the standard methods of rock mechanics testing and measurement as well as interpretation of data in practice Explains connections between main parameters both empirically as well as on the basis of scientific theory Provides examples of the practice of rock mechanics to major engineering projects Practical Rock Mechanics teaches from first principles and aids readers understanding of the concepts of stress and stress transformation and the practical application of rock mechanics theory.
