资源简介：
Newmark analyses of lateral spreading induced by liquefaction were conducted using a database of 22 documented case histories. Site stratigraphy and SPT values for the liquefiable soil were based upon the case-history documentation. The yield acceleration was estimated based on post-liquefaction residual shear strength estimated using three different correlations with SPT blow count. Representative acceleration time histories were selected from time histories recorded in the earthquake. The probabilistic analysis using a truncated normal distribution indicates that the lateral spreading displacement calculated using the Olson and Johnson correlation will be no more than twice the reported displacement with a confidence of 97%.
