A Study on Stress Waves in Rock Masses With Multiple Parallel Fractures Using Distinct Element Method

Abstract

In this paper, stress waves in rock masses with multiple parallel fractures applied by sine load are studied with rigid block and face-to-face contact model of distinct element method (DEM). Normal stress waves in a rock pillar are analyzed, and the wave patterns of different damping ratio are presented. The effects of silent boundary conditions, soft interlayer and tensile property on the propagation characteristics of stress waves are analyzed.
