Book Description
Solutions for soil engineering and soil-structure interaction problems need realistic and pertinent experimental and modelling tools. In this work, extensive developments proposed by the invited speakers of the Lyon International Symposium held in September 2003 are presented, including experimental investigations into deformation properties; laboratory, in-situ and field observation interpretations; behaviour characterisation and modelling; and case histories. The contributions include recent investigations into anisotropy and non-linearity, the effects of stress-strain-time history, ageing and time effects, yielding, failure and flow, cyclic and dynamic behaviour. In addition, advanced geotechnical testing is applied to real engineering problems, and to ways of synthesising information from a range of sources while engaging in practical site characterisation studies.

Book Description
This book presents a complete and comprehensive analysis of the behaviour of granular materials including the description of experimental results, the different ways to define the global behaviour from local phenomena at the particle scale, the various modellings which can be used for a D.E.M. analysis to solve practical problems and finally the analysis of strain localisation. The concepts developed in this book are applicable to many kinds of granular materials considered in civil, mechanical or chemical engineering.
Book Description
Cette thèse sur le comportement des matériaux granulaires traités aux liants hydrocarbonés a été réalisée au Département Génie Civil et Bâtiment (DGCB) de l'Ecole Nationale des Travaux Publics de l'Etat. Elle s'inscrit dans le cadre d'une collaboration avec la société TOTALFINAELF. Une partie de cette thèse a été réalisée dans le cadre du programme RILEM WG3 du TC 182 pour l'étude de la fatigue des enrobés bitumineux. Certains aspects ont également fait l'objet d'une collaboration avec le Laboratoire Central des Ponts et Chaussées (LCPC). La première partie de cette thèse concerne une étude bibliographique sur les matériaux bitumineux, la fatigue des enrobés bitumineux et le phénomène d'autoréparation. La deuxième partie présente la campagne expérimentale réalisée lors de cette thèse. On présente la mise au point et la validation d'un essai homogène en Traction-Compression, adapté à l'étude de la fatigue des enrobés bitumineux. L'essai est réalisé à température et à fréquence constantes (10°C et 10 Hz), en mode de contrainte ou de déformation imposée. Seize formulations différentes ont été testées. Une étude menée sur les différents critères visant à prédire la durée de vie en fatigue des enrobés bitumineux est présentée. L'approche du DGCB pour le calcul des taux d'endommagement, a été appliquée sur les résultats de la campagne expérimentale. Grâce à cette approche, l'influence de plusieurs paramètres de formulation des enrobés bitumineux sur le comportement en fatigue a été mise en évidence. Parallèlement, une partie de la campagne expérimentale a été réservée pour explorer le phénomène d’autoréparation. Une série d’essais a été effectuée sur trois formulations différentes en introduisant des périodes d’arrêt de sollicitation. Finalement, Dans la dernière partie de cette thèse, une loi de dommage par fatigue est proposée. Cette loi est intrinsèque et basée sur la méthode du DGCB. Elle prend en considération la correction des effets parasites sur les valeurs du module et l'évolution non linéaire de l'endommagement dans les essais de fatigue.

Book Description
This title provides a comprehensive overview of elastoplasticity relating to soil and rocks. Following a general outline of the models of behavior and their internal structure, each chapter develops a different area of this subject relating to the author's particular expertise. The first half of the book concentrates on the elastoplasticity of soft soils and rocks, while the second half examines that of hard soils and rocks.

Book Description
This book addresses the latest issues in multiscale geomechanics. Written by leading experts in the field as a tribute to Jean Biarez (1927-2006), it can be of great use and interest to researchers and engineers alike. A brief introduction describes how a major school of soil mechanics came into being through the exemplary teaching by one man. Biarez's life-long work consisted of explaining the elementary mechanisms governing soil constituents in order to enhance understanding of the underlying scientific laws which control the behavior of constructible sites and to incorporate these scientific advancements into engineering practices. He innovated a multiscale approach of passing from the discontinuous medium formed by individual grains to an equivalent continuous medium. The first part of the book examines the behavior of soils at the level of their different constituents and at the level of their interaction. Behavior is then treated at the scale of the soil sample. The second part deals with soil mechanics from the vantage point of the construction project. It highlights Biarez's insightful adoption of the Finite Element Codes and illustrates, through numerous construction examples, his methodology and approach based on the general framework he constructed for soil behavior, constantly enriched by comparing in situ measurements with calculated responses of geostructures.

Book Description
The work of geotechnical engineers contributes to the creation of safe, economic and pleasant spaces to live, work and relax all over the world. Advances are constantly being made, and the expertise of the profession becomes ever more important with the increased pressure on space and resources. This book presents the proceedings of the 15th Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XV PCSMGE), held in Buenos Aires, Argentina, in November 2015. This conference, held every four years, is an important opportunity for international experts, researchers, academics, professionals and geo-engineering companies to meet and exchange ideas and research findings in the areas of soil mechanics, rock mechanics, and their applications in civil, mining and environmental engineering. The articles are divided into nine sections: transportation geotechnics; in-situ testing; geo-engineering for energy and sustainability; numerical modeling in geotechnics; foundations and ground improvement; unsaturated soil behavior; embankments, dams and tailings; excavations and tunnels; and geo-risks, and cover a wide spectrum of issues from fundamentals to applications in geotechnics. This book will undoubtedly represent an essential reference for academics, researchers and practitioners in the field of soil mechanics and geotechnical engineering. In this proceedings, approximately 65% of the contributions are in English, and 35% of the contributions are in Spanish or Portuguese.
