Increasing demand of railways has led to the construction of new railway lines and upgradation of existing tracks. It is essential to construct high embankments for connecting these lines. Embankment layers are subjected to heavy axle loads due to which slopes face the risk of failure. Reinforcing embankment with geogrid is a suitable way to overcome this problem. This study investigates the seismic slope stability of railway embankment. For this purpose, railway embankment as specified by Research Design and Standards Organisation (RDSO) has been modelled using finite elements. Axle load of train has been taken as point load to simulate railway loading. Maximum deformation and factor of safety has been computed for various heights of embankment. Pseudo static analysis has been performed to evaluate the dynamic performance of railway embankment. Effectiveness of geogrid reinforcement for enhancement of stability has been evaluated. The number and spacing of geogrid layers have been varied.
