Analysis of Properties of Broken Rock
YANG Mi-jia
HE Yong-nian
Abstract：Based on the analysis of broken rock structure, the relation between broken rock strength and itsdifferent structures was discussed, and some useful results were obtained. The research shows that the mag-nitude and direction of inner stresses on the broken surface of a rock sample are different from those of thestresses on the boundary of the rock sample and change with loading stresses, and the strength of brokenrock is determined by inner stress on the broken surface and loading stresses on a rock block. Rock usuallyfails along the broken surface, but sometimes it maybe fails across the rock block. And a new method, whichmay be united with the normal FEM method, was given.
