DEM simulation of dry granular flow in laboratory flume tests

摘要

This paper presents the results of experimental and numerical simulations of fast slope movements by 1g scale model tests. The soil used for modeling is a mono-granular medium sand. The aim is to gain insights into the understanding of these phenomena for the prediction of the run-out distance and of the impact forces on obstacles. Also of interest is the validation of Discontinuum Element Modelling (DEM), when used for the same purposes. The experimental set-up comprises a flow channel with the photogrammetric method being adopted to obtain particle displacements and velocities.
