Three-Dimensional Numerical Analyses of Pile Response Due to Unstrutted Excavation-Induced Lateral Soil Movement
The behavior of a single pile subject to excavation-induced soil movement is investigated using the explicit finite difference code, FLAC3D. The Modified-Cam Clay Constitutive Model was employed to model the non-linear stress-strain soil behavior, and the pile was assumed to have linear elastic behavior. The interface model incorporated in FLAC3D code was used to simulate the soil/pile contact. The built-in ‘fish' language was used to calculate the data demanded. The results given by the numerical analysis indicate that the pile deflection, bending moment and lateral soil pressure increase with increasing excavation depth and decrease with the increasing distance from the excavation face. The retaining wall stiffness, the pile stiffness, the pile head condition and the length of pile exert important effect on the pile response. Compared with the above, the effect of the axial load on the pile response is less. The research finding was compared with other published case history and reasonably good agreement was found between them.
