as a function of normal stress on artificial fractures, and found the highly non-linearity of joint closure curves. On the basis of a large number of laboratory experiments on natural rock joints, BANDIS et al... itself, the deformation of joint walls must be subtracted from the measured total deformation of the joint specimens. Artificial joints with different row number of asperities were compressed at the half......
infill on the shear behavior of rock joints, and remarkable test results were obtained. ZHU [17] used artificial joints made of high gypsum to investigate the mechanics of rock joint with different first... were 7 cm×7 cm×7 cm. A series of Brazilian tensile tests were performed to split the cubes and manufacture artificial joint specimens, as shown in Figure 1. The mechanical parameters of granite used......
