摘要
By using 3D ANSYS software, the transverse action mechanism of rock bolts in discontinuous rock mass was analyzed. The deformation process of discontinuous rock mass restricted with a rock bolt was simulated. The laws of interaction between a rock bolt and rocks and the displacement of discontinuous rock mass and a rock bolt were obtained. An unusual characteristic phenomenon of a rock bolt, called the railway function of rock bolt, was discovered in shearing. This function is harmful to the stability of discontinuous rock mass by rock bolting.
