The design of reinforced-soil wall is very crucial under seismic condition, in which the soil amplification is a very important factor. Most of the researchers had analysed the reinforced-soil wall considering the effect of soil amplification for non-cohesive soils using the pseudo-dynamic approach. Very few researchers had analysed the reinforced-soil wall with a cohesive backfill along with the effect of soil amplification. In this paper, the pseudo-dynamic approach has been used to find out the seismic stability of reinforced-soil wall considering the effect of soil amplification for cohesive soil backfill with uniform surcharge. The effect of shear strength parameters, soil-wall adhesion, number and length of reinforcement layers and seismic coefficients of ground accelerations on the stability of reinforced-soil wall is critically examined. Variation in mobilised pullout resistance of reinforcement layers, and factor of safety with time is also considered. For cohesionless backfill without soil amplification factor, numerical predictions are in good agreement when compared with available studies in literature for validation purpose.
