Proceedings of sessions of the GeoShanghai Conference, held in Shanghai, China, June 6-8, 2006. Hosted by Shanghai Society of Civil Engineering, China. In cooperation with the Geo-Institute of ASCE; Georgia Institute of Technology; the University of Kansas; the University of Tennessee; International Association of Foundation Drilling; Deep Foundation Institute; Saga University; and Delft University of Technology.

This Geotechnical Special Publications contains 42 papers on unsaturated soil mechanics and environmental geotechnics. The book begins with two state-of-the-art papers on geoenvironmental engineering and unsaturated soil mechanics applied to field problems. Additional papers highlight unsaturated soil phenomena, coupled phenomena, and transport phenomena. The book showcases new experimental evidence and theoretical developments on strength and deformational behaviors of both expansive soil and collapsible loess, as well as some new testing techniques to characterize volumetric change and strength of these problematic soils. It reports on the latest understanding of various coupled phenomena in soils such as hydrobiological, hydromechanical, hydrothermal, thermal-mechanical and hydrochemical coupling. The papers also address the latest advances in geoenvironmental applications including the sustainability of landfills, removal of various contaminants from soils, soil-contaminant interactions, and soil stabilization.
