NUMERICAL ANALYSIS FOR SEISMIC EVALUATION OF RETAINING WALLS CONSISTING OF CONCRETE PANELS AND BACKFILL REINFORCED WITH GEOGRIDS

Abstract

In this study, the seismic behavior of the retaining wall consisting of concrete panels and backfill reinforced with geogrids is evaluated based on the dynamic elasto-plastic FEM. A series of shaking table tests and a test construction of retaining wall of a real scale are performed for the verification of the analyses. Based on the above, a rational analytical technique for seismic evaluation of retaining walls reinforced with geogrids is proposed.
