【Abstract】This study investigated the influence factors on the seismic response and deformation modes of retaining walls using large-scale model shaking table tests.Experimental results showedthat the distribution of peak seismic earth pressures along the height of a wall was a single peak value curve. The seismic earth pressures on a gravel soil retaining wall were larger than the pressures on the weathered granite and quartz retaining walls. Also, the peak seismic earth pressure increased with increases in the peak ground acceleration and the wall height.The measured seismic active earth pressures on a rock foundation retaining wall were larger than the calculated values,and the action position of resultant seismic pressure was higher than 0.33 H. In the soil foundation retaining wall, the measured seismic earth pressureswere much smaller than the calculated values,while the action position was slightly higher than 0.33 H. The soil foundation retaining wall suffered base sliding and overturning under earthquake conditions,while overturning was the main failure mode for the rock foundation retaining walls.
