Abstract
An analytic procedure for predicting threshold accelerations for movement of gravity wall bridge abutments due to earthquake loading is described. The method draws on previous work related to the sliding mode of failure, and a newly developed theory on seismic reduction of bearing capacity. The main contribution of this paper is to present laboratory observations verifying mode of failure and critical acceleration levels predicted by this procedure for model retaining wall bridge abutments subjected to seismic excitation on a shaking table. Three different test series were performed with different interface conditions between the wall, and the bridge deck, soil foundation, and backfill resulting in a variety of modes of wall deformation.
