The purpose of this study is to perform to earth pressure coefficient calculation simulation using the Distinct Element Method (DEM). Earth pressure theory has been established since long ago and is still in use. Therefore, simulation based on Coulomb and Rankine's theory of earth pressure is carried out to confirm usability of DEM. As a result of the static earth pressure coefficient calculation simulation, good results were obtained. However, in the passive earth pressure coefficient calculation simulation, theoretical results were not obtained. In order to investigate the cause, it is necessary to increase the simulation pattern and determine the appropriate condition.
