The Mechanically Stabilised Earth (MSE) retaining wall is used as an alternative designed structure for conventional cast-in-place concrete type walls and gravity walls. The MSE wall behaves as a coherent block considered as flexible, which can sustain loading types and deformations due to the interaction between the backfill and the inclusion materials. The construction of MSE walls is cost effective, requires less site preparation, and is technically more feasible. MSE wall behaviour highlydepends upon type of reinforcement and backfill used in the system.However, use of backfill with high fine content and poor drainage behavior can cause excessive wall movement or even failure.In the present study, MSE wall was modelled using finite element numerical tool PLAXIS 2D, to study the effect of backfill and reinforcement on MSE wall behaviour.Wall deformations were analysed by varying soil parameters such as, soil friction angle and unit weight soil of retained and foundation soil.It was observed that, as the friction angle of the foundation soil increased, wall deformations were reduced.Also, it was seen that, length of the reinforcements has significant effect on wall deformations.Deformations were reduced as the length of reinforcements increased.
