<p>In recent years, road collapse, which is thought to be caused by aged deterioration of sewer pipes, is occurring in various places, and from now on, there is concern that road collapse damage tends to increase with increasing aging pipeline. In this study, a three-dimensional numerical analysis coupled with Smoothed Particle Hydrodynamics (SPH) and Distinct Element Method (DEM) is conducted to elucidate the road caving collapse caused by damage of sewer pipe. It is attempted to construct a model that can analyze from dry soil to unsaturated soil and saturated soil by considering the apparent cohesive force associated with water content in the method of the previous study.</p>
