Numerical Simulation of Granular Flows in a Large Flume Using Discontinuous Deformation Analysis

A long run-out rock avalanche is dened as an extremely rapid, massive, flow-like motion of fragmented rock derived from a bed-rock failure. Due to their extraordinary mobility, rock avalanches have been extremely costly in terms of human lives and of engineering developments, and have interested many researchers. Numerical method appears a promising approach for analyzing most of the physical aspects of dry rock avalanches and for predicting the consequence of real events as well.
