Abstract: A three-dimensional finite element simulation is presented in this study to investigate the lateral pile response for single vertical pile embedded in cohesionless soil. Four water table cases we simulated, i.e., dry soil condition, water table in the base and middle of the pile length and fully saturated soil. Linear elastic model of pile is used for modeling the pile material while Mohr-Coulomb model is used to simulate the surrounding soil. The pile-soil interaction are composed of 16-node interface elements. It was found that the water table elevation influence on the behavior of laterally loaded pile. As expected the case of dry soil condition gives more resistance than other three soil cases.
