Based on the existing cascading experiment of collapsed soil using large scale slope model, characteristics of flow behavior was analyzed as well as that of impulsive behavior. Moreover, applicability of particle method (MPM) to evaluate impulsive action was conducted a study as well as the method to evaluate fluid force. As soil model, sandy soil and crushed stone were used. As a result, it is found that difference of flow behavior according to soil properties is caused by the difference of flow behavior such as either sliding or rolling depending on friction coefficient and inclination of slope, and that the analysis using MPM can reproduce flow behavior, sedimentation behavior and the impulsive action well by setting the realistic value based on the material tests resulting as an analysis parameter, and that the method to evaluate impulsive load by the fluid force might become the evaluation of the dangerous side depending on soil properties.
