Excavation in close proximity to preexisting structures is a prevalent occurrence within urban environments. The implementation of supporting excavation techniques is crucial in order to mitigate the risk of potential structural damage to nearby buildings. Numerous elements exert influence on the choosing of the supporting system. Several factors influence the behavior of soil, including the type of foundation, the foundation level of neighboring buildings, the water table level, and the budget allocated to the ongoing construction project. This study’s overarchingobjective is to analyze how a model secant pile wall behaves when loaded with a footing load at different depths on sandy soil. Under different loading situations, the study analyzes the link between the maximum lateral displacement of the wall and the depth of the footing for cantilever secant pile walls and anchored secant pile walls. The study uses a constant wall-to-footing-edge-to-width ratio of 0 and a deferent depth to width ratio of (0.5, 1, 1.5, and 2) as its variables. The experimental findings indicate that augmenting in the depth of the neighboring footing can result in a rise in the lateral displacement of the wall.
