This study aims to clarify the applicability of Distinct Element Method to pile drive simulation. In this study, element spring constant are determined by Hertz’s elastic contact theory, and ground model are created by free fall method. Four different ground models and three pile models were used in calculation. In each computation, relative displacements of pile and force distribution in ground were assessed. From the comparison with these results of analysis, effect of boundary, ground model size and pile driving force became clear.
