摘要

．采用二维多边形离散元法(DEM)研究了岩石形状和初始方位对岩崩现象的影响。在模拟中，将具有相同质量但不同形状的岩石颗粒从相同的高度投放到直线斜坡上，研究其平移动能和旋转动能以及跳动距离的变化。不同岩石角度和纵横比下的参数化研究表明，岩石形状和初始方位对跳动距离有显著影响。

The effect of particle shape on rockfall events

. The effects of rock shape and initial orientation on the rockfall phenomena are studied using a two-dimensional polygonal discrete element method (DEM). In the simulation, rock particles with the same mass but different shapes are dropped from the same height onto a straight slope to investigate the variations in both translational and rotational kinetic energies and the runout distance. Parametric studies under varied angularity and aspect ratio of the rock revealed a significant effect of rock shape and initial orientation on the runout distance.
