Soil Behavior and Geo-Micromechanics (GSP 200) contains 41 papers addressing many different areas of soil behavior, constitutive modeling, and geo-micromechanics. The papers in this Geotechnical Special Publication range from experimental studies of soil shear strength and compressibility to theoretical advances in Biot's consolidation theory and constitutive modeling. The research described in this proceedings advances our understanding of soil as an engineering material and improves our ability to model the behavior of soil in slopes, foundations, and earth structures. The papers in this publication were presented during the GeoShanghai 2010 International Conference held in Shanghai, China, June 3-5, 2010.|Soil Behavior and Geo-Micromechanics (GSP 200) contains 41 papers addressing many different areas of soil behavior, constitutive modeling, and geo-micromechanics.
