of jointed rock mass; test results show that the fractal dimension of rock joints can be related to the equivalent cohesion strength and shear strength of the rock mass. When the fractal dimension of the joint surface is less than critical dimension Dc 1.404, the cohesion strength and shear strength of the rock mass increase as the fractal dimension increases; for larger fractal dimensions, all......

and then decreases. LIU et al [19] found that the inclination of the bolt has a significant impact on the shear strength and shear deformation, and a larger inclination angle is conducive to exerting the dowel shear force of the bolt. SPANG et al [20] concluded that inclined bolts can increase the shear strength to 90% of the ultimate tensile load. LUDVID et al [21] analyzed the influence......
