Abstract— Retaining walls shall be designed to withstand lateral earth and water pressures, the effects of surcharge loads, the self-weight of the wall and in special cases, earthquake loads. Retaining walls are used to prevent retained material from assuming its natural slope Estimation of the active earth pressure acting on a segmental retaining wall is very important in the design of many geotechnical engineering structures, particularly retaining walls. In this present study, a numerical simulation of a reinforced earth wall is described and a parametric study using a finite element method is conducted to investigate the performance of the wall under both static and seismic conditions. The damage of retaining wall under seismic forces has been due to the increase in the pressure resulting from the movement of the structure during earthquake. Wall movement and pressure depends on the response of the soil behind the wall, the response of the subsoil. In case of Fly ash it is observed that by replacing the Fly ash as a retained fill instead of soil, lateral earth pressure decreases about 75% in static condition and about 55% in dynamic condition. It is also observed that by replacing the Fly ash as a retained fill instead of soil, there is a sufficient decrease about 35% in the displacement of the wall in static condition and largely decrease about 75% in dynamic condition. The proposed numerical model intended to study the effect of Fly ash on the lateral earth pressure and displacement of the wall.
