Abstract: After anchoring rock and soil with anchor rod, whether the anchoring solid unit can provide enough anchoring force is the key of the whole anchoring project.The existing research shows that the failure mode of an anchoring system is mainly occurring at the interface between bolt and anchoring agent and the interface between anchoring agent and surrounding rock, which are the vulnerable link in the anchoring system.This paper summarized the factors that affect the interfacial mechanical properties of anchorage bolt and analyzed the main problems in this research field.It was pointed out that the rational use of numerical simulation and combination of test methods and theoretical analysis was helpful to understanding the mechanism of anchorage system and had great significance to improving the safety and stability of anchorage engineering.It provided the direction and reference for the future research on the mechanical properties of anchor bolt interface.
