Simulation Of Lateral Spreading And Evaluation Of Lateral Displacement Of Gently Sloping Liquefied Ground

This paper is focused on the simulation of the lateral spreading phenomenon and the anticipated maximum surface displacements of sloping ground. An innovative numerical methodology is proposed employing a generalized plasticity model implemented in a finite element code (Chan, 1988) which has been thoroughly validated against VELACS centrifuge liquefaction experiments (Arulanandan & Scott, 1993). The results of numerical analysis compared with experimental measurements indicate that the proposed numerical model has the capability to simulate the lateral spreading phenomenon. This model has been used for a parametric study. In parametric analyses, different factors have been investigated and their effects on magnitude of soil deformation have been studied.
