Influence of “X” Fracture, Confining Pressure, and Temperature on Rock Masses’ Failure Process

Influence of “X” Fracture, Confining Pressure, and Temperature on Rock Masses’ Failure Process

Based on the similarity theory, sandstone was taken as the prototype, and rock-like specimens were made with the strength ratio of 1 : 1. Single “X” fracture and double “X” fractures were prefabricated in rock-like specimen, and crack propagation was studied through the compressive test. An improved...
