Abstract
It is one of the most important problems to judge anchoring force of constant resistant bolt in anchoring support. This involves the properties of rock, binder and bolt material as well as the interaction among them in the process of stress. In this paper, a series of numerical experiments have been carried out by using the software "Real Failure Process Analysis (RFPA)", which is suitable for the study of complex mechanism of nonlinear and discontinuous media. Four factors that affect the anchoring force of constant resistance bolt are analyzed, the whole process of mechanical failure of anchored rock with constant resistance bolt is monitored, and the failure mode of anchored rock under different conditions is revealed. Draw a few conclusions with reference significance.
