Finite Element Method (FEM) in Open Digging with Sheet Pile on Soft Soil

Abstract

Slope excavated is an excavation that is carried out by making a slope on the excavated side of the soft soil, which functions to withstand the lateral or horizontal forces towards the excavation. The excavation stability analysis is carried out by modeling the finite element method to determine the displacement that occurs in the existing bored pile structure, and soil behavior around the bored pile foundation due to the slope excavated method with drained conditions on the excavation with a slope of 1: 1.25. The resulting deformation value is 52.95 cm, the excavation safety factor value is 1.16, and the lateral bored pile deformation value is 2.10 cm. Bored pile with a diameter of 1200 mm can be maintained by doing an alternative treatment using sheet pile as slope reinforcement, so that the slope stability safety value meets the requirements to be 1.75.
