This collection of thirty-seven papers represents the state of the practice in soft ground engineering. These technical papers cover laboratory and field characterization of soft ground, soft ground microstructure, stabilization methods, embankments, tunneling, geosynthetics, environmental aspects of soft ground, design and prediction methods, and behavioral mechanisms of soft soils. Several large construction projects are presented as case histories and recent developments in soft ground research are emphasized with data reported from field test sites from around the world.
