In order to study the effects of temperature and shear rate on the fracture mechanism of resin anchorage interface, a variable temperature shear test device was used to shear test the anchor specimens. Based on digital correlation technique (DIC) and scanning electron microscopy (SEM), the evolution mechanism and microscopic failure characteristics of shear interface cracks were analyzed. The results show that the peak shear stress at the interface between anchor and anchoring agent decreases with the increase of temperature and shear rate. As the rib angle of the bolt increases, the climbing phenomenon at the anchoring interface gradually weakens, and the peak shear stress at the anchor-anchor interface gradually increases. Temperature, shear rate and rock compressive strength have great effects on the fracture evolution of anchorage-rock specimens and the variation of peak shear stress at anchorage-rock interface. The results of this study provide a reference value for the analysis of the failure mechanism of the anchoring interface.
