Clay behaviour is affected by coupled mechanical and chemical processes occurring in them at various scales. The peculiar chemical and electro-chemical properties of clays are the source of many undesired effects. These papers provide insight into the variables controlling clay behaviour.
Geological materials are inherently discontinuous because of joints, faults, shears, bedding, and foliation planes which typically transect the rock mass. Over the past two decades enormous effort has been made by the rock mechanics community to quantify the characterization of rock structure by developing better geo-statistical tools and by developing more general constitutive laws for the mechanical strength of discontinuities. Along with these developments a substantial effort has been made to develop better and more suitable numerical methods, which allow realistic modelling of discontinuous deformation in geological materials. In particular, the discrete element method (DEM), the combined discrete-finite element methods (FEM/DEM), and discontinuous deformation analysis (DDA) have reached a mature development stage. In this book 24 high quality, peer-reviewed papers on discontinuous analysis in geological materials, written by leading experts from 17 countries, are presented in six chapters: 1) Key note lecture, 2) Plenary lectures, 3) Case studies in rock slope and underground openings in discontinuous rock, 4) Analysis, response, prediction, and monitoring of existing rock and stone monuments, 5) Validation of theoretical models, 6) Theoretical developments in modelling discontinuous deformation. It is believed that the collection of papers in this volume demonstrates the directions in which theoretical developments in analysis of discontinuous deformation should proceed, the validity and limitations of existing codes, and the range of engineering problems to which discontinuous analysis can be applied.
These proceedings address engineering issues related to vibratory pile driving and deep soil compaction. Also included are keynote lectures and the documentation of an international vibratory class-A prediction event.
Until the publication of this new book there had been a lack of well-founded guidelines for evaluating concentrations of lead in soil and its relationship to human health. Thus, much confusion has existed among regulatory agencies, industries, public health officials, and the medical community about the evaluation and remedying of lead-contaminated soils. Lead in Soil: Recommended Guidelines represents the combined efforts of a multi-disciplinary international task force from the Society for Environmental Geochemistry and Health (SEGH) whose members are experts in the fields of lead pollution and toxicology. It provides an international consensus concerning environmental lead and blood lead-especially in children. The task force evaluated the evidence and made recommendations for guidelines to appraise lead concentration. It also studied the influence of soil and other sources of lead on blood lead concentrations. A model was prepared that allows the user to select appropriate target levels of blood lead while allowing for a variety of environmental situations or regulatory criteria.

Knowledge of the mechanical properties of rocks at high pressure and temperature is fundamental not only for material science but also for earth science, such as for solving the mechanism of earthquakes and tectonic processes. For example, physical bases of the earthquake prediction based on the rock mechanics have been proposed, and extensive seismological, geophysical and geochemical observations have been conducted to find precursory phenomena before large earthquakes. However, we cannot help telling for the present that we do not have sufficient knowledge of an effective and reliable method for earthquake prediction. The book is mainly concerned with comprehensive source of information on the mechanical properties and behavior of rocks under high pressure that scans current state-of-the-art knowledge and shows contribution in establishing an experimental basis for the understanding of the mechanism of rock deformation in the earth's interior. The book can be used as textbook for graduate students by university teachers to prepare courses and seminars, and for active scientists and engineers who want to become familiar with a fascinating new field.

Vibroflotation is a method of ground improvement up to depths of 40 metres. It has been successfully used since 1936 but the major problem with this method is that in spite of the fact that it performs well, nobody can explain how it works. The techniques for checking the quality of the compaction during vibration are unreliable, making the method as a whole unquantifiable and unmeasurable. This title explores the problems surrounding the method, looking at deep compaction, plastodynamics and the Riemann problem amongst other issues, showing the reader what information from the movement of the vibration can be used as an additional quality control and to assess effectiveness.
This text presents the mechanical aspects of reinforced soil (RS) behaviour. Beginning with simple reinforced soil models, it discusses various aspects of this material, such as properties of its constituents, and stresses and strains in reinforced soil, up to the more complex analysis of RS structures. Its scope and level ensures it will be a valuable resource for students, academics and geotechnical engineering professionals alike.
The problems and procedures facing the practising geotechnical engineer are becoming increasingly complex, relying heavily on numerical models and analysis by specialized software packages. This book provides in-depth coverage of a wide range of geotechnical subjects normally found only in more specialized literature. Using clear illustrations and numerous worked examples, the book explains core, yet highly complex topics such as critical state modelling, centrifuge modelling, pressuremeter testing and finite element modelling. Aimed at the geotechnical student and practising engineer, it should enable the reader to make informed judgements about appropriate analytical parameters and allow for greater understanding of results and their implications.
Reinforced concrete (R/C) is one of the main building materials used worldwide, and an understanding of its structural performance under gravity and seismic loads, albeit complex, is crucial for the design of cost effective and safe buildings. Concrete Buildings in Seismic Regions comprehensively covers of all the analysis and design issues related to the design of reinforced concrete buildings under seismic action. It is suitable as a reference to the structural engineer dealing with specific problems during the design process and also for undergraduate and graduate structural, concrete and earthquake engineering courses. This revised edition provides new and significantly developed coverage of seismic isolation and passive devices, and coverage of recent code modifications as well as notes on future developments of standards. It retains an overview of structural dynamics, the analysis and design of new R/C buildings in seismic regions, post-earthquake damage evaluation, pre-earthquake assessment of buildings and retrofitting procedures, and several numerical examples. The book outlines appropriate structural systems for many types of buildings, explores recent developments, and covers the last two decades of analysis, design, and earthquake engineering. It specifically addresses seismic demand issues and the basic issues of structural dynamics, considers the "capacity" of structural systems to withstand seismic effects in terms of strength and deformation, and highlights the assessment of existing R/C buildings under seismic action. All of the material has been developed to fit a modern seismic code and offers in-depth knowledge of the background upon which the code rules are based. It complies with European Codes of Practice for R/C buildings in seismic regions, and includes references to current American Standards for seismic design. |
