Abstract
Over the past decade, the focus of liquefaction engineering began to shift towards assessment of the consequences of liquefaction with respect to the seismic performance of engineered structures and facilities, which requires accurate and reliable tools for prediction of ground deformations over the small to moderate range. Promising new predictive tools are evolving. These include simplified, empirical tools as well as sophisticated analytical and constitutive models. Recently, a high quality laboratory testing program consisting of undrained, cyclic simple shear testing on fully-saturated samples of Monterey No. 0/30 sand was completed at U.C. Berkeley. As a result, a new semiempirical procedure was proposed for predicting post-liquefaction volumetric reconsolidation ground settlements in essentially level ground (α ≈ 0 conditions). This new procedure also includes modification for predicting liquefaction-induced ground settlement in sloping or near free-face ground (α ≠ 0 conditions). The new procedure was shown to perform well for a suite of field performance case histories with small-to-moderate ground settlements, comparing with existing semi-empirical engineering tools for estimating liquefaction-induced ground deformations.
