A model of the shear beam-Winkler spring-retaining wall system is employed to describe the interaction between the backfill and the wall. The wall is assumed to be a rigid body and undergoes horizontally translational and rocking motions. A set of coupled integro-partial differential equations describing the vibration of the whole system is reduced into a set of coupled ordinary differential equations by employing Galerkin's method. Then the model analysis is served to solve the equations. For certain cases the frequencies and the corresponding mode shape are calculated. The force and moment on the wall during design earthquake are also presented. The significance of the effect of wall motion on the responses is also shown.
