Granular flow analysis considering soil strength using moving particle simulation method

Abstract

In recent years, many sediment-related disasters have occurred in Japan. To predict the sediment flow, granular flow analysis was conducted with the moving particle simulation method, using the viscosity term formulated by the Drucker-Prager model. The program code used is Particleworks Ver. 6, developed by Prometech Software. Plastic viscosity is described as a function of (cohesion) c and Φ (the shear resistance angle). Simple problems, such as freestanding height and dam breakage of the simulations were analyzed to assess the accuracy of the particle simulation method with the model.
