Strength Characteristics and Failure Mechanism of Granite with Cross Cracks at Different Angles Based on DIC Method
Advances in Materials Science and Engineering
The engineering rock mass is generally composed of the rock matrix and structural plane and is an anisotropic inhomogeneous geological body. Accidents such as roof collapse and well caving caused by joint and fissure expansion occur frequently during tunnel excavation and service, resulting in serious casualties and economic losses. It is of great theoretical significance and engineering value to study the fracture mechanism of the jointed rock mass to ensure the stability of the surroundingdoi:10.1155/2022/9144673 fatcat:vwzfdoslwfcrbmcxj5vtnqoosy
