Ground Failures Under Seismic Conditions

by Shamsher Prakash

Proceedings from sessions of the ASCE National Convention, held in Atlanta, Georgia, October 9-13, 1994. Sponsored by the Geotechnical Engineering Division of ASCE. This collection contains 15 invited and contributed papers focusing on the the behavior of silty and gravelly soils under seismic loading. Recent case histories, some of which are presented in this volume, reveal that silty and gravelly soils may liquefy, and such failures have resulted in landslides, lateral spreading, and damage to buildings. The papers present an overview of the dynamic properties, cyclic behavior, and liquefaction of silty and gravelly soils. Special emphasis is given on the effect of nonplastic and plastic fine content on the cyclic behavior and strength of saturated silty and gravelly soils. Results are presented for partially saturated collapsible soils, demonstrating susceptibility to liquefaction of cyclic softening. Current laboratory and field testing methods are discussed, including the in-situ soil freezing sampling technique and in-situ cyclic testing. Finally, simplified and refined methods of analysis for the prediction of settlements and seismic behavior of soil masses are examined through a series of case studies.
