- Abstract
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 the main joint has rarely influence on the stress-strain curve of the rock mass, the stress when the first fine crack comes up and the peak; when the angle between the minor joint and the main joint is not changing, the peak value gradually reduces as the direction angle between the main joint and the load varying from 0º to 90º; when the peak comes up, the direction angle between the main joint and the load is 45º or 90º, the varying angle between the minor joint and the main joint has rarely influence on the development of the number of new fine cracks, while the angle between the main crack and the load is 0º, the impact on the development of the number of new fine cracks is obvious.
