Effect of Lateral Stiffness on Propped Embedded Retaining Walls’ Structure

The present work investigates the effects of lateral stiffness on propped embedded retaining walls. The deflection of a retaining wall is affected by many aspects such as loading on the outside of the excavation, strength, type and stiffness of the soil, embedded depth, retained height, type and stiffness of the retaining wall, and the water table. This work focuses on impact of different types of stiffness of the retaining wall and excavation depth. The comparative finite element analysis (FEA) of 2-D and 3-D embedded retaining walls was studied considering the effects of lateral stiffness. The total displacement of soil and wall displacement was evaluated. The results show that with an increase in the wall stiffness the displacement reduces and the lateral stiffness reduces the central maximum displacement of soil.
