Abstract

This paper simulated 7 kinds of rock uniaxial compression fracture under different homogeneity (each sample size is 3) by RFPA. According to the results of numerical simulation, the failure of rock is analyzed as follow. The study results indicate that with the increase of homogeneity degree, precursory information of the main fracture is significantly reduced, and the stronger of the brittle fracture, the macroscopic fracture mode performance is a concentrated fracture shape. On the contrary, then it will show some diffusivity. Under the same degree of homogeneity conditions, the macro-strength of rock with a certain statistical law, but there is a certain dispersion of the fracture mode.
