000011023 520__ $$2eng$$aThe use of pseudo-static methods for the evaluation of soil thrust acting on retaining wall under seismic condition is well established in the design of such structures. But the most common design method is still based on the limit equilibrium of the soil wedge without taking into account the presence of the wall. This paper presents a new solution based on the pseudo-static equilibrium of the soil-wall-reinforcements system which considers horizontal acceleration. The developed solution takes into account the effect of the presence of the wall and reinforcements. Stability analyses are conducted to determine the required strength of reinforcements and critical inclination of the failure angle. Parametric studies illustrate the effects of seismic acceleration on the design of reinforced retaining wall and also the forces in the reinforcements. The force of reinforcements required to resist direct sliding increase rapidly as the seismic acceleration increases. A detailed design example is included to illustrate usage of proposed procedures.
