Based on the fractal simulation of rock joints, two types of numerical direct shear test models of rock joints were established, and the scale effect and the infill effect of the shear strength parameters of the rock joint were studied by using the numerical test method. The results of the first type of numerical direct shear test show that the critical joint size (CJS) exists by which the scale effect of the shear strength parameters of the rock joint can be eliminated. With the increase of the fractal dimension of the rock joint, the scale effect becomes more outstanding and...
