Proceedings of Uncertainty '96, held in Madison, Wisconsin, July 31-August 3, 1996.

This Geotechnical Special Publication (GSP 58) contains 86 papers presenting the state-of-the-art in analytical and design methods that incorporate uncertainty in the geologic environment. Particular emphasis is placed on practical applications where quantifying uncertainty and risk associated with the geologic environment plays an important, if not dominant, role in analysis and design. The role of uncertainty in the geologic environment is illustrated through numerous examples involving field data as well as several case histories. Quantitative assessments of uncertainty are illustrated for site chartacterization, variability in soil and rock properties, dams and stability, earth structures and foundations, geoenvironmental applications, and seismic assessment and dynamics. The application of models for analyzing uncertainty in the geologic environment also is presented.
