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.Content: Chapter 1 Jean Biarez (pages 1-14): Jean?Louis Bordes, Jean?Louis Favre and Daniel GrimmChapter 2 From Particle to Material Behavior (pages 15-34): Bernard Cambou and Cecile Nouguier?LehonChapter 3 Granular Materials in Civil Engineering (pages 35-82): Etienne FrossardChapter 4 Waste Rock Behavior at High Pressures (pages 83-112): Edgar Bard, Maria Eugenia Anabalon and Jose CampanaChapter 5 Models by Jean Biarez for the Behavior of Clean Sands and Remolded Clays at Large Strains (pages 113-152): Jean?Louis Favre and Mahdia HattabChapter 6 The Concept of Effective Stress in Unsaturated Soils (pages 153-182): Said Taibi, Jean?Marie Fleureau, Sigit Hadiwardoyo, Hanene Souli and Antonio Gomes CorreiaChapter 7 A Microstructural Model for Soils and Granular Materials (pages 183-220): Pierre?Yves HicherChapter 8 Modeling Landslides with a Material Instability Criterion (pages 221-242): Florent Prunier, Sylvain Lignon, Farid Laouafa and Felix DarveChapter 9 Numerical Modeling (pages 243-332): Arezou Modaressi?Farahmand?RazaviChapter 10 Evaluating Seismic Stability of Embankment Dams (pages 333-392): Jean?Jacques Fry
