Influence of Joint Set with Different Angles on Rock Behaviour and Cavern Stability
Using DDARF method, the uniaxial and biaxial compression experiments of double-fractured rock samples are numerically investigated. Influences of different fracture angles and confining pressures on behaviour of rock samples are studied. Moreover, the fracture process, the crack initiation stress, and the peak strength of the fractured rock under both uniaxial and biaxial compression tests are obtained. The results are used to obtain the strength envelope and to analyze the rock stability of an underground project as a case study.
