The object of this study is to provide the fundamental data for the impact resistant design of concrete check dams. At first, DEM was developed so as to simulate the impact phenomenon of concrete. Then, the impact response and failure of a model test and an actual concrete check dam under debris flow was simulated. As a result, it is found that the model using DEM can simulate well the impact response and failure patterns of a check dam under debris flow. INTRODUCTION The
