摘要：

A simulation method to calculate deformation of submerged rubble mound structures is presented. The method consists of Volume of Fluid method(VOF) and Discrete Element Method(DEM). The method is verified by physical model experiments using glass spheres. The fluid force and setting method of DEM parameters are carefully examined. An effective method to consider shape of rubble is also presented. The method can simulate the deformation of submerged nibble mound structures substantially.
