...Y. Zhang; Y. Jiang; C. Wang; M. Chen; Q. Yin The instability of rock slopes and underground engineering is usually caused by the shear failure of non-persistent joints. Rock bolt, as the main support method, has an important influence on the shear behaviour of joints. However, the shear behaviour...
