Piezocone and cone penetration tests (CPTu and CPT) applications in foundation engineering includes different approaches for determining the bearing capacity of shallow foundations, along with methods for determining pile bearing capacity and settlement concepts. The use of soft computing (GMDH) neural networks related to CPT records and Geotechnical parameters are also discussed. In addition, different cases regarding the behavior of foundation performance using case records, such as shallow foundation, deep soil improvement, soil behavior classification (SBC), and bearing capacity are also included.

Analysis, Design and Construction of Foundations outlines methods for analysis and design the construction of shallow and deep foundations with particular reference to case studies in Hong Kong and China, as well as a discussion of methods used in other countries. It introduces the main approaches used by geotechnical and structural engineers, and the precautions required for planning and designing foundation structures. Some computational methods and computer programs are reviewed to provide tools for performing more realistic analysis of foundation systems. The authors examine in depth the methods used for constructing shallow foundations, deep foundations, excavation and lateral support systems, ground improvement techniques, and ground monitoring for proper site management. Some new and innovative foundation construction methods are also introduced. It is illustrated with case studies of failures and defects from actual construction projects. It is ideal for consulting geotechnical engineers.

Model Uncertainties in Foundation Design is unique in the compilation of the largest and the most diverse load test databases to date, covering many foundation types (shallow foundations, spudcans, driven piles, drilled shafts, rock sockets and helical piles) and a wide range of ground conditions (soil to soft rock). All databases with names prefixed by NUS are available upon request. This book presents a comprehensive evaluation of the model factor mean (bias) and coefficient of variation (COV) for ultimate and serviceability limit state based on these databases. These statistics can be used directly for AASHTO LRFD calibration. Besides load test databases, performance databases for other geo-structures and their model factor statistics are provided. Based on this extensive literature survey, a practical three-tier scheme for classifying the model uncertainty of geo-structures according to the model factor mean and COV is proposed. This empirically grounded scheme can underpin the calibration of resistance factors as a function of the degree of understanding - a concept already adopted in the Canadian Highway Bridge Design Code and being considered for the new draft for Eurocode 7 Part 1 (EN 1997-1:202x). The helical pile research in Chapter 7 was recognised by the 2020 ASCE Norman Medal.

This book covers the field of applied geotechnology related to all aspects of construction in ground, including compacted fill, excavations, ground improvement, foundations, earth retaining systems and geotechnical site characterization.

Distinctively it covers the identification of problematic soils and appropriate mitigation measures, and the inspection of ground construction work. It combines the technical and the practical in applied geotechnology.

Explosives Engineering by Paul W. Cooper presents the basic technologies used in the engineering of explosives and explosion systems. The book’s six sections cover the chemistry of explosives, energetics of explosives, shock waves, detonation, and initiation and initiators. An understanding of basic physics, chemistry, mechanics, and mathematics through calculus is assumed. Concise descriptions of the physical processes and underlying theory are expressed in terms as useful for the designer or analyst as for the engineer. Special features include solved problems in each technical area, extensive data on explosive materials and their properties and behavior, and many useful reference lists and bibliographies. This book will help engineers, scientists, and students acquire the engineering tools needed to understand, analyze, and solve a broad range of explosion problems and design applications. It also will interest crime and accident scene investigators, and anyone concerned with the regulatory and environmental issues involved in the transportation, storage, and commerce of explosive materials.

Devised with a focus on problem solving, "Geotechnical Problem Solving" bridges the gap between geotechnical and soil mechanics material covered in university Civil Engineering courses and the advanced topics required for practicing Civil, Structural and Geotechnical engineers. By giving newly qualified engineers the information needed to apply their extensive theoretical knowledge, and informing more established practitioners of the latest developments, this book enables readers to consider how to confidently approach problems having thought through the various options available. Where various competing solutions are proposed, the author systematically leads through each option, weighing up the benefits and drawbacks of each, to ensure the reader can approach and solve real-world problems in a similar manner

The scope of material covered includes a range of geotechnical topics, such as soil classification, soil stresses and strength and soil self-weight settlement. Shallow and deep foundations are analyzed, including special articles on laterally loaded piles, retaining structures including MSE and Tieback walls, slope and trench stability for natural, cut and fill slopes, geotechnical uncertainty, and geotechnical LRFD (Load and Resistance Factor Design).

This volume brings together a selection of key papers by this soil mechanics pioneer. The papers have been selected on the basis of their importance in the development of soil mechanics and to highlight the nature and range of subjects that Bishop investigated during the thirty-seven years of his career. Bishop's most influential paper was presented at an ASCE (American Society of Civil Engineers) conference in Boulder, Colorado, in 1960, and while it made a big impression at the time, it is now in danger of disappearing from sight. In addition, two of Bishop's very significant papers were published in the late 1970s in the Philosophical Transactions of the Royal Society, not normal reading for the soil mechanics fraternity, and thus became known to only a few people. That has remained the case to this day, and the fact that these two papers have not been republished was the initial motivation for creating this volume. In addition, it is nearly 40 years since Bishop retired from his professorial position at Imperial College and a fitting time to remember Bishop with both a biography, The Bishop Method, and this volume of his papers. In addition to the Bishop papers, there is a paper by Laurie Wesley and Richard Pugh reflecting their research with Bishop. Separate papers were to have been written after the completion of their PhDs, with Bishop as the lead author, but because of his illness this didn't happen. The opportunity has now been taken to present the comprehensive research in these papers, as a tribute to their supervisor and mentor.

This is a revised and updated edition of the highly successful first and second editions. In the intervening period the procedures used in the description of soils and rocks have continued to develop and evolve and this new edition incorporates changes in the international standards EN ISO 14688 and 14689 and those resulting in the national standard, BS 5930:2015 and the 2020 amendment thereof. Close comparison is also made with US practice in description (ASTM D2488) and classification (ASTM D2487). Significant changes in rock description are included – the reintroduction of the Approaches 1 to 5 for rock weathering; Approach 1 for description and Approaches 2 to 5 (Rock Weathering Working Party) for classification when appropriate and helpful. Also covered is the reintroduction of the 12.5 MPa boundary and the term moderately weak in rock strength description: a significant boundary in design in rock. The book continues to provide invaluable practical guidance in carrying out engineering geological logging of soil and rock samples and exposures in the field. The systematic and codified approach is laid out in detail to ensure the defined descriptors are used in a consistent format, rendering mistakes less likely and the necessary communication from field to design more successful. The procedures, techniques and tips within this book continue to serve and guide young practitioners learning their craft, but also their seniors and mentors, including responsible experts who sign off the logs and report on behalf of their company. More than ever, the need to be aware of current practices in order in order to avoid costly mistakes is paramount.

Craig's Soil Mechanics continues to evolve and remain the definitive text for civil engineering students worldwide.

The consequences of a large dam failing can be disastrous. However, predicting the performance of concrete dams during earthquakes is one of the most complex and challenging problems in structural dynamics. Based on a nonlinear approach, "Seismic Safety Evaluation of Concrete Dams" allows engineers to build models that account for nonlinear phenomena such as vertical joint slippage, cracks, and cavitation. This yields more accurate estimates. Advanced but readable, this book is the culmination of the work carried out by Tsinghua University Research Group on Earthquake Resistance on Dams over the last two decades.

Based on the work of the WASHCost project run by the IRC International Water and Sanitation Centre (IRC), this book provides an evaluation of the water, sanitation and hygiene (WASH) sectors in the context of developing countries and is the first systematic study of applying the life-cycle cost approach to assessing allocations. It presents unit cost estimates of the WASH sector across geographic locations and technologies, including rural and peri-urban areas, and these are compared with service levels. It analyses detailed data from more than 5000 households across nine agro-climatic zones in Andhra Pradesh State in India. Key issues assessed include poverty analysis of service levels, cost drivers and factors at the village and household level, and governance aspects such as transparency, accountability and value for money in relation to unit costs and service levels. This is the most comprehensive study of the WASH sector in India and elsewhere that utilises the life-cycle cost approach, along with GIS, econometric modelling and qualitative research methods. Not only does it contribute to research and methodology in this area, but the analysis also provides valuable insights for planners, policy makers and bi-lateral donors. The authors show how the methodology can also be applied in other developing country contexts.

Earthquake engineering is the ultimate challenge for structural engineers. Even if natural phenomena involve great uncertainties, structural engineers need to design buildings, bridges, and dams capable of resisting the destructive forces produced by them. These disasters have created a new awareness about the disaster preparedness and mitigation. Before a building, utility system, or transportation structure is built, engineers spend a great deal of time analyzing those structures to make sure they will perform reliably under seismic and other loads. The purpose of this book is to provide structural engineers with tools and information to improve current building and bridge design and construction practices and enhance their sustainability during and after seismic events. In this book, Khan explains the latest theory, design applications and Code Provisions. Earthquake-Resistant Structures features seismic design and retrofitting techniques for low and high raise buildings, single and multi-span bridges, dams and nuclear facilities. The author also compares and contrasts various seismic resistant techniques in USA, Russia, Japan, Turkey, India, China, New Zealand, and Pakistan.

This book teaches the principles of soil mechanics to undergraduates, along with other properties of engineering materials, to which the students are exposed simultaneously. Using the critical state method of soil mechanics to study the mechanical behavior of soils requires the student to consider density alongside effective stresses, permitting the unification of deformation and strength characteristics. This unification aids the understanding of soil mechanics. This book explores a one-dimensional theme for the presentation of many of the key concepts of soil mechanics - density, stress, stiffness, strength, and fluid flow - and includes a chapter on the analysis of one-dimensional consolidation, which fits nicely with the theme of the book. It also presents some theoretical analyses of soil-structure interaction, which can be analyzed using essentially one-dimensional governing equations. Examples are given at the end of most chapters, and suggestions for laboratory exercises or demonstrations are given.

Embankment construction projects on very soft soil often give rise to serious problems. This volume on geotechnics and soft soil engineering therefore treats all phases of the design and construction process exhaustively, from the first investigation step to the monitoring of constructed work. The book presents the development concepts necessary for the project stages and discusses in great detail construction methods, displacement estimations, stability analyses, monitoring, and various other aspects involved. Extensive attention is furthermore paid to the application of geosynthetics as a tool to improve the stability of soft soils and embankments. Including various tables and practical data for many geographical areas in the world, this reference volume is essential reading for engineers and researchers in geotechnical engineering, construction, and related disciplines.

There are other books on unsaturated soil mechanics, but this book is different. Unsaturated soil mechanics is only one aspect of a continuous range of soil mechanics studies that extends from the rheology of high water content soil slurries to the mechanics of soft soils, to stiff saturated soils, to unsaturated soils, and, at the far end of the range, to dry soils. In reality, the water content of all soils, that are not permanently submerged, varies seasonally. In most climatic zones, rainfall varies during the year and the depth of the water table varies sympathetically. In applying unsaturated soil mechanics in practice, it is therefore important to realise and allow for the probability that soil will, either seasonally or occasionally, pass from the unsaturated to the saturated state and even from unsaturation to dryness. This is the only book that looks specifically at this essential practical aspect. The theory of unsaturated soils is fully dealt with in all of its aspects, including its application to natural undisturbed soils and compacted soils. Application of the theory to soil-like materials such as mine waste and municipal solid waste is also covered. Application of the theory to practice is illustrated by a number of detailed case histories. Unsaturated soil mechanics principles can also successfully and usefully be applied in related fields such as the bulk storage of particulate materials, underground mine support, solution mining and concrete structures. Several case histories are given that illustrate these practical applications. The author has been professionally engaged in practical research and application of unsaturated soil mechanics for close to 60 years and with this book shares his wide experience with the reader.

Rock mechanics is a multidisciplinary subject combining geology, geophysics, and engineering and applying the principles of mechanics to study the engineering behavior of the rock mass. With wide application, a solid grasp of this topic is invaluable to anyone studying or working in civil, mining, petroleum, and geological engineering. Rock Mechanics: An Introduction presents the fundamental principles of rock mechanics in a clear, easy-to-comprehend manner for readers with little or no background in this field. The text includes a brief introduction to geology and covers stereographic projections, laboratory testing, strength and deformation of rock masses, slope stability, foundations, and more. The authors-academics who have written several books in geotechnical engineering-have used their extensive teaching experience to create this accessible textbook. They present complex material in a lucid and simple way with numerical examples to illustrate the concepts, providing an introductory book that can be used as a textbook in civil and geological engineering programs and as a general reference book for professional engineers.

This book 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.

Reliability-based design is the only engineering methodology currently available which can ensure self-consistency in both physical and probabilistic terms. It is also uniquely compatible with the theoretical basis underlying other disciplines such as structural design. It is especially relevant as geotechnical design becomes subject to increasing codification and to code harmonization across national boundaries and material types. Already some codes of practice describe the principles and requirements for safety, serviceability, and durability of structures in reliability terms. This book presents practical computational methods in concrete steps that can be followed by practitioners and students. It also provides geotechnical examples illustrating reliability analysis and design. It aims to encourage geotechnical engineers to apply reliability-based design in a realistic context that recognises the complex variabilities in geomaterials and model uncertainties arising from a profession steeped in empiricism. By focusing on learning through computations and examples, this book serves as a valuable reference for engineers and a resource for students.

This book provides a thorough review of this powerful and sophisticated technique for modelling soil structure interactions. It has been written by an international team of authors.

This is a compehensive text covering the fundamentals of the theory of plasticity in the context of geomechanics, including the mathematical formulation of various constitutive theories as well as aspects of numerical integration.

The identification of meso-scale phenomena - occurring between microscopic and continuum length scales - has been one of the most exciting developments in rock mechanics in the last decade. Meso-scale phenomena are considered as the bridge between the two length scales in understanding shear between material interfaces as well as particulate systems and in studying material response. Examples are the initiation of seismic slip along fault planes at great depths at rates nearing shock conditions, and the initiation and rapid runout of landslides near the earth's surface. Additionally, the basic physics of thermo-poro-mechanical coupling can be elucidated through a meso-scale mechanics approach as a means of understanding the loss of shearing resistance when water and heat are trapped inside almost impervious clay layers under great pressure. This book presents a collection of 21 current, peer-reviewed articles on shear physics at the meso-scale in earthquake and landslide mechanics, authored by leading international experts in the field. Contributions are grouped in 5 chapters, discussing (1) the dynamics of frictional slip, (2) fault gauge mechanics, (3) experimental fault zone mechanics, (4) granular shear and liquefaction, and (5) landslides' dynamics. This research area has broad applications to the fields of earth sciences and geoengineering, with immediate bearing on our understanding of both earthquake and landslide mechanics, two geological processes that pose great risk to man kind worldwide.

Fracture and flow of rocks under stress and their geophysical and seismological implications raise fundamental questions in rock mechanics, particularly in the areas of tectonophysics and seismology. This text exclusively addresses the deformation and fracture of rock specimens under general triaxial compression, in which all three principal stresses are different; which significantly affects the ultimate strength of rocks. It moreover deals with deformation and failure following intermediate principal stress in graphic and numerical form. The effect of the intrinsic features of rock masses of inhomogeneous or anisotropic structure are taken into account, as are acoustic emission phenomena in rocks under various stress states. Friction in rocks, measured by a newly-designed shear-testing machine, is discussed in relation to earthquake phenomena.
