Proceedings of sessions of GeoShanghai 2010, held in Shanghai, China, June 3-5, 2010. Hosted by Tongji University, China; Shanghai Society of Civil Engineering, China; Chinese Institution of Soil Mechanics and Geotechnical Engineering, China. In cooperation with Alaska University Transportation Center, USA; Geo-Institute of ASCE, USA; Deep Foundation Institute, USA; East China Architectural Design and Research Institute Company, China; Georgia Institute of Technology, USA; Nagoya Institute of Technology, Japan; Transportation Research Board, USA; University of Newcastle, Australia; University of Illinois at Urbana-Champaign, USA; University of Kansas, USA; University of Tennessee, USA; Vienna University of Natural Resources and Applied Life Sciences, Austria. This Geotechnical Special Publication contains 41 papers addressing many different areas of soil behavior, constitutive modeling, and geo-micromechanics. Papers cover topics ranging 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 understanding of soil as an engineering material and improves our ability to model the behavior of soil in slopes, foundations, and earth structures.
