Based on it, a rational approach was exploredsystematically for quantitative evaluation of large post-liquefaction deformation ofsaturated sand from aspects of physical fundamentals, constitutive model, numericalimplementation and practical application.

Study on uplift behavior of pipelines based on post-liquefaction deformation method;

Numerical modeling of liquefaction-induced deformation in sand;

Main framework and topics of seismic liquefaction study are summarized,including the current state of the art and trends,with respect to mechanism of liquefaction,susceptibility of liquefaction,liquefaction flowslides,liquefaction-induced deformation and numerical modeling techniques.
