42015-03-31 , 法政大学大学院デザイン工学研究科
In this paper, modeling for the simulation of the avalanche by a particle method is discussed. There are two kinds of the snow avalanches, one is the surface avalanche which shows a smoke-like flow, and another is the total-layer avalanche which shows a flow like Bingham fluid. In the simulation of the surface avalanche, the particle method in consideration of a rotation resistance model is used. The particle method by Bingham fluid is used in the simulation of the total-layer avalanche. At this time, the plastic viscosity of Bingham fluid is shown from the creep factor and the Glide coefficient of the snow which can be found from an experiment.
