Abstract
A numerical analysis was carried out for a rigid retaining wall experiencing earthquake loading. The seismic forces acting on the wall was determined by simulating both sinusoidal load as well as the earthquake time history of an actual earthquake. At first considering that the backfill consists purely of sandy soils, the failure zone and the resulting earth pressure were calculated. After observing the failure zone of such backfill, the domain is substituted by lightweight Expanded Polystyrene (EPS) geofoam. The effect of replacing the sand with such lightweight materials on the developed seismic thrust is then examined. The results show that the use of the EPS geofoam as a replacement renders as much as 50% to 60% reduction of the seismic thrust.
