Two different approaches are used to estimate pore pressures and settlement in a 50-ft (15.2-m) sand deposit subjected to a variety of earthquake loadings. Although the two approaches seem consistent in predicting the occurrence of liquefaction, the results show that they are quite divergent in estimating pore-pressure build-ups and magnitude of ground settlement.
The basic definitions of, and the differences between, currently available soil models are reviewed. These models are applied to site response analyses where two depths and two levels of base input motion are considered. Computational results are presented and compared with regard to the effects of using different soil models on computed site response. Other implications resulting from the choice of soil model for seismic response analysis are also discussed.
