Abstract
A simple method of analysis which allows both the earthquake induced forces and displacements of retaining structures to be computed are presented. The method considers both the weight of the wall and the flexibility and strength of both the backfill and foundation soil. A single degree of freedom elastic-plastic model is used and the equation of motion is integrated to yield the time histories of wall force and displacement. The method is applied to a gravity retaining wall structure subjected to three different acceleration time histories. The results indicate that: (1) the dynamic displacements will be small for walls having the usual static factor of safety against sliding ≥ 1.5; (2) the maximum dynamic force on the wall increases as the factor of safety against sliding increases and can be greater than the Mononobe-Okabe value when sliding is prevented from occurring.
