Proceedings of the Second International Conference on Geotechnical and Earthquake Engineering, held in Chengdu, China, October 25-27, 2013. This collection contains 92 peer-reviewed papers on challenges and recent advances in geotechnical and seismic research and practice. Topics include: soil dynamics and earthquake engineering, foundation engineering and pile testing, excavation and shoring, embankments and retaining walls, tunnels and underground structures, dams and levees, slopes and landslides, expansive soils and loess, geology and rock mechanics, ground improvement techniques, geotechnical numerical modeling and computation, and geotechnical support technologies during construction. GSP 232 will be of interest to geotechnical researchers and practicing engineers around the world working on geotechnical earthquake engineering problems.
