The rock structure is extremely complex, it is difficult to reflect the mechanical properties and the relevant failure mechanisms truly under loads whatever by the theoretical analysis or the laboratory test. In order to analyze the damage characteristics of the crossover jointed rock mass from the microscopic point, the discrete method PFC2D was used to simulate the damage mechanism in the assured jointed rock numerically under Axial compression. The results show that when the angle of the main joint is consistent with the direction of the load, the varying angle between the minor joint and t...
