Numerical Simulation of the Seismic Response of Gravity Retaining Walls
In this study, the analysis of the seismic response of a soil-retaining wall system is performed based on a three-dimensional microscale framework utilizing the discrete element method (DEM). The proposed method is employed to investigate the seismic response of gravity-type retaining walls with three degrees of freedom. In the simulation, the granular soil deposit is idealized as a collection of spherical soil particles; the retaining wall is simulated as a rigid block composed of clumped particles to yield the physical characteristics of a typical retaining wall. The computational model captured some of the dynamic characteristics typically observed from the response of retaining walls. For instance, time histories of the resultant lateral thrust on the wall show that its magnitude varies as the wall moves relative to the backfill and its location changes as well.
