Abstract

A method that is proposed by the authors accomplished to reduce the amount of computation to predict the amount of lataral ground flow compared to conventional Finite Element Method by assuming deformation mode of liquefied ground, a definition of potential energy, and modeling the liquefied sand as viscous fluid. The accuracy of the method has been evaluated by some examples of lateral ground flow that was caused by earthquakes. However, evaluation of its accuracy has been impossible in time domain. Therefore, the method is applied to shaking table test on subsidence of embankment and foundations to quantitatively evaluate the accuracy in time domain in this paper, and the existence of reasonable viscosity of the liquefied sand was confirmed.
