A numerical study on true triaxial strength and failure characteristics of jointed marble
To investigate the strength and failure characteristics of rock mass, 3D discrete element method (DEM) is used in this study to conduct numerous simulated true triaxial compression tests on jointed marble. Three series of tests are carried out to study the influence of the intermediate principal stress and the joint inclined angle on the macroscopic mechanical characteristics. The DEM simulation results reveal that the strength and failure mechanism have a strong dependency on the intermediate principal stress except for the specimen with the inclined angle of 60° and the joint parallel to the intermediate principal stress direction. In addition, the influence of the joint inclined angle on the strength and failure characteristics is significant except for the specimen with the joint parallel to the minimum principal stress direction. Tensile cracks are the dominant failure mechanism. Based on a 3D true triaxial failure criterion, the simulated strength data can be predicted using four empirical parameters.
