摘要：
In this study, the uniaxial compression test and PFC2D numerical simulation were carried out on the artificial rock specimen with T-shaped prefabricated fractures. The effects of the lengths 11, 12 of the main fractures, the length 13 of the secondary fracture, and the angle /3 between the secondary fracture and the loading direction on the uniaxial compressive strength and crack evolution law of specimen were studied. The research results show that the change of 11, 12 and /3 has obvious effect on the compressive strength and crack growth of the specimen, but the change of 13 has little effect on the compressive strength of the specimen. When 13 = 40 mm and 11 & NOTEQUAL; 12, the angle /3 influences on the crack propagation and failure mode of the specimen.
