Abstract

The essence of failure for compression-shear sliding unstable rock belongs to the fracture of dominant fissure. The fracture mechanics model of compression shear type dangerous rock is established by combining rock failure criterion with fracture strength factor; By equivalent stress method, the equivalent stress field of the non - parallel section of the main control surface is obtained; The failure criterion of compression shear type dangerous rock is derived by using the classical D-P failure theory.
