Progressive failure model is based on certain failure criteria to check whether there is a unit in the material damage, to destroy the unit, the use of the stiffness degradation and stiffness reconstruction method for processing.
Conclusions Through this paper, the numerical model is set up, can better simulate the rock material under the action of water pressure and load crack propagation of irregular extension process.
