Abstract

The dynamic reaction of the natural type of retaining wall is quite complex. Wall development and pressure rely upon the reaction of the soil underneath a retaining wall and the reaction of the backfill. The greater part of the present knowledge of the dynamic reaction of the wall has originated from the model test and numerical analysis. This paper aims to know the behavior of the retaining wall and the backfill. Also, under the effect of machine foundation, numerical modeling is used concerning a method of finite element. Two amplitudes of machine foundation subjected to three frequencies were used. The model used in the finite element was the linear elastic model (LE) for foundation and the Mohr-Coulomb model (MC) for soil. The results of this analysis for the amplitude of 25 kPa, the lateral displacement was 75% more than the active for the case of the amplitude of 40 kPa, the lateral displacement was 125% more than the active, and for the case of the velocity of 30 mm /sec very far higher than the maximum permissible velocity is 2.5 mm/sec and the acceleration was decreased by 52% between machine foundation and retaining wall.
