Key Features: - Sequentially explains soil modeling techniques for easy understanding - Demonstrates the use of an effective stress equation based on data from porous-solid models. - Explains how porous-solid models can simulate the soilwater retention curves of materials. - Establishes an elastoplastic framework for the volumetric behavior of unsaturated soils that is used to simulate the phenomenon of collapse upon wetting and the behavior of expansive soils. - Explains the practical application of fully a coupled hydro-mechanical (critical state) soil model - Includes scientific references for further reading.

The third edition includes additional information on retention curves in deforming curves, the application of a coupled hydro-mechanical model simulating undrained tests and the behavior of soils during static compaction, and the use of a porous-solid model to develop a fully analytical equation for the relative hydraulic conductivity of soils. The new chapters also cover the experimental parameters used to derive the models. This edition also updates material from previous editions, and adds new scientific references. Towards A Unified Soil Mechanics Theory paves the way for a universal theory of soil mechanics that has a wide range of applications. The book is a valuable reference to civil engineers, geotechnical engineers, earth scientists and hydrologists interested in soil mechanics at both academic and professional levels.

Ground improvement has been one of the most dynamic and rapidly evolving areas of geotechnical engineering over the past forty years. Moreover, increasing development of sites with marginal soils has made ground improvement an increasingly important core component of geotechnical engineering curricula. This textbook addresses the latest and most effective techniques for ground improvement, at a level designed for undergraduate and graduate-level university students and practitioners seeking fundamental background in these techniques. Thus, Fundamentals of Ground Improvement Engineering is for students and professionals. The book is written to, first, broadly introduce key ground improvement methods and, second, to provide readers with a thorough understanding of the theory, design principles, and construction approaches that underpin each method. Major topic areas covered include compaction, grouting, vibratory methods, soil mixing, stabilization and solidification, cut-off walls, dewatering, consolidation, geosynthetics, and earth retention. The book contains numerous problems and worked examples, and is well illustrated with photographs, schematics, charts and graphs.The rich companion website provides instructor resources and videos of the techniques, which are useful for students and for professionals to show clients.
