Soils can rarely be described as ideally elastic or perfectly plastic and yet simple elastic and plastic models form the basis for the most traditional geotechnical engineering calculations. With the advent of cheap powerful computers the possibility of performing analyses based on more realistic models has become widely available. One of the aims of this book is to describe the basic ingredients of a family of simple elastic-plastic models of soil behaviour and to demonstrate how such models can be used in numerical analyses. Such numerical analyses are often regarded as mysterious black boxes but a proper appreciation of their worth requires an understanding of the numerical models on which they are based. Though the models on which this book concentrates are simple, understanding of these will indicate the ways in which more sophisticated models will perform.

The Critical State Framework for Soil Behaviour: New insight from DEM Simulations presents the latest on a topic that was originally proposed by Schofield and Wroth in the 1960s, and has subsequently proven to be a very good framework to describe sand behavior. This framework uses the critical state, the void ratio and stress level attained by a soil at large shear deformations, as a reference state. The particulate discrete element method (DEM) allows the fundamental basis of the critical state to be examined in detail. Using DEM simulations, this book considers the sensitivity of the critical state to particle scale parameters (friction) and overall conditions (3D stress state), also linking between overall behavior and particle scale mechanics. The simulation data is then analyzed to better understand the fundamental mechanisms. Contains critical analysis of the way in which DEM simulations should be run to obtain meaningful data for soil mechanics studies Documents data obtained using more than one DEM code / software and parametric studies that give new insight into the factors that govern the position of the critical state line Demonstrates the ability of DEM to capture the critical state and the dependency of the material response on the state parameter (as proposed by Jefferies and Been)

This Book Brings Out The Possibilities Of Generalizations Of Behaviour Of Soils And Hence Of Predicting The Required Engineering Properties Without Elaborate Testing. We Recognize That A Single Approach Cannot Be Evolved For All Soil Types And Hence The Necessity For Classifying Soils Into Different Categories And To Use Appropriate Model For Each. First Of All, Based On Mechanism Of Stress Transfer And Interaction Between The Phases, Two Obvious Classes, The Fine Grained And Coarse-Grained Soils Have Been Differentiated.The Discussions Bring Out That Because Of Identical Mode Of Stress Transfer, The Mechanical Behaviour I.E., Compressibility, Shear Strength Relations, Permeability Variations Etc. Can Be Generalized For All Fine Grained Soils, Enabling The Prediction Of Behaviour Of Such Soils With Just The Knowledge Of Certain State And Index Properties. The Sequence Of Discussion Is On The Characterization Of Specific Soil States And Prediction Of Proportion Starting From The Ideal Saturated Uncemented Soils, Both Normally And Over Consolidated, Cemented Saturated Soils And Partly Saturated Soils.In Dealing With The Behaviour Of Coarse Grained Soils, The Importance Of Microfabric And The Difficulties In Possible Generalizations Are Discussed. Perhaps The Unique Feature Of This Book Is That The Division Of The Chapters Is Based On Different Soil States, All The Mechanical Behaviours Being Discussed Under Each Soil State.The Book Will Be Of Interest To Both Academicians And Practising Engineers, Researchers And Postgraduate Students. It Would Serve As A Textbook For Undergraduate Students With Prior Knowledge Of Basic Soil Mechanics.

Covering the undergraduate course in geotechnical engineering for civil engineers, this work sets out the basic theories of soil mechanics in a clear, simple way, combining both classical and critical state theories. By using short, focused chapters, the author ensures an accessible text while maintaining a continuous thread running through the book as theory develops into application. The treatment of soil mechanics is essentially theoretical but it is not highly mathematical and soil behaviour is represented by relatively simple equations with clearly defined parameters. The theory is supported by worked examples and simple experimental demonstrations.

An understanding of the mechanical properties of unsaturated soilsis crucial for geotechnical engineers worldwide, as well as tothose concerned with the interaction of structures with the ground.This book deals principally with fine-grained clays and silts, orsoils containing coarser sand and gravel particles but with asignificant percentage of fines. The study of unsaturated soil is a practical subject, linkingfundamental science to nature. Soils in general are inherentlyvariable and their behaviour is not easy to analyse or predict, andunsaturated soils raise the complexity to a higher level. Evenamongst practicing engineers, there is often lack of awareness ofthe intricacies of the subject. This book offers a perspective ofunsaturated soils based on recent research and demonstrates howthis dovetails with the general discipline of soil mechanics. Following an introduction to the basic soil variables, thephases, the phase interactions and the relevance of soil structure,an up-to-date review of laboratory testing techniques is presented.This includes suction measurement and control techniques intriaxial cell testing. This is followed by an introduction tostress state variables, critical state and theoretical models inunsaturated soils. A detailed description of the thermodynamic principles asapplied to multi-phase materials under equilibrium conditionsfollows. These principles are then used to explore and develop afundamental theoretical basis for analysing unsaturated soils. Soilstructure is broken down into its component parts to developequations describing the dual stress regime. The critical statestrength and compression characteristics of unsaturated soils areexamined and it is shown how the behaviour may be viewed as athree-dimensional model in dimensionless stress-volume space. Theanalysis is then extended to the work input into unsaturated soilsand the development of conjugate stress, volumetric andstrain-increment variables. These are used to examine themicromechanical behaviour of kaolin specimens subjected to triaxialshear strength tests and lead to observations not detectable byother means. Unsaturated Soils: A fundamental interpretation of soilbehaviour covers a rapidly advancing area of study, researchand engineering practice and offers a deeper appreciation of thekey characteristics of unsaturated soil. It provides students andresearchers with a framework for understanding soil behaviour anddemonstrates how to interpret experimental strength and compressiondata. provides engineers with a deeper appreciation of keycharacteristics of unsaturated soils covers a rapidly advancing area of study, research andengineering practice provides students and researchers a framework for understandingsoil behaviour shows how to interpret experimental data on strength andcompression the limited number of books on the subject are all out ofdate

"This introductory course on soil mechanics presents the key concepts of stress, stiffness, seepage, consolidation, and strength within a one-dimensional framework. Consideration of the mechanical behaviour of soils requires us to consider density alongside stresses, thus permitting the unification of deformation and strength characteristics. Soils are described in a way which can be integrated with concurrent teaching of the properties of other engineering materials. The book includes a model of the shearing of soil and some examples of soil-structure interaction which are capable of theoretical analysis using one-dimensional governing equations. The text contains many worked examples, and exercises are given for private study at the end of all chapters. Some suggestions for laboratory demonstrations that could accompany such an introductory course are sprinkled through the book." --Book Jacket.

A Rigorous and Definitive Guide to Soil Liquefaction Soil liquefaction occurs when soil loses much of its strength or stiffness for a time—usually a few minutes or less—and which may then cause structural failure, financial loss, and even death. It can occur during earthquakes, from static loading, or even from traffic-induced vibration. It occurs worldwide and affects soils ranging from gravels to silts. From Basic Physical Principles to Engineering Practice Soil Liquefaction has become widely cited. It is built on the principle that liquefaction can, and must, be understood from mechanics. This second edition is developed from this premise in three respects: with the inclusion of silts and sandy silts commonly encountered as mine tailings, by an extensive treatment of cyclic mobility and the cyclic simple shear test, and through coverage from the "element" scale seen in laboratory testing to the evaluation of "boundary value problems" of civil and mining engineering. As a mechanics-based approach is necessarily numerical, detailed derivations are provided for downloadable open-code software (in both Excel/VBA and C++) including code verifications and validations. The "how-to-use" aspects have been expanded as a result of many conversations with other engineers, and these now cover the derivation of soil properties from laboratory testing through to assessing the in situ state by processing the results of cone penetration testing. Downloadable software is supplied on www.crcpress.com/product/isbn/9781482213683 Includes derivations in detail so that the origin of the equations is apparent Provides samples of source code so that the reader can see how complex-looking differentials actually have pretty simple form Offers a computable constitutive model in accordance with established plasticity theory Contains case histories of liquefaction Makes available downloads and source data on the CRC Press website Soil Liquefaction: A Critical State Approach, Second Edition continues to cater to a wide range of readers, from graduate students through to engineering practice.
