Effects of Wall Height on Stress Distribution in a Soil Wall Reinforced with Geosynthetics

The superiority of geosynthetics over other reinforcements has led to the introduction of retaining walls reinforced with geosynthetics as an important option in the design of retaining walls. The lack of problems such as corrosion, rust, better engagement with materials, and ease of implementation are advantages of this approach. Soil retaining walls reinforced with geosynthetics are generally designed based on the limit equilibrium method. In this method, the effect of factors such as specific boundary conditions, tough reinforcement, and type of facing are not considered. The present study used the finite element method with PLAXIS 2D software to develop several 2D models under plane strain conditions. The results showed that horizontal displacement and vertical settlement were strongly influenced and their values increased dramatically as wall height increased. The maximum axial forces created in the reinforcement and the lateral soil pressure increased as the wall height increased.
