Soil and Rock Behavior and Modeling represents the latest advances in the static and dynamic behavior of soils and rocks, including constitutive modeling and numerical methods. This Geotechnical Special Publication contains 65 international papers that were presented at the GeoShanghai Conference held in Shanghai, China from June 6-8, 2006. The book begins with two keynote articles that discuss soil constitutive modeling. The first section of the book discusses theoretical concepts and experimental procedures of soil behavior and laboratory testing. The second section's papers span from advanced concepts in rock mechanics to the interactions in constructed facilities. It also includes numerical applications of problems in rocks. The third section focuses on modeling soil behavior, with many of the papers using field and laboratory experimental data to verify their findings. Finally, the fourth section discusses the latest advances in soil and soil structure interactions under dynamic excitation. It contains results from work using shaking tables, wave induced loading, vibrations and numerical simulations.
