Accurate site characterization is one of the most important aspects of a successful geotechnical design. This volume provides a summary of current advances in data acquisition, management, and interpretation, as contributors describe specific cases of how progress in these areas has improved accuracy of site characterization. Peer-reviewed papers detail construction of TINS from borehole data; acquisition, reduction and management of data for consolidation testing; and management of the geotechnical data for a tunnel near Paris, France, among other topics.
