The shear stress constitutive equation of an anchorage interface element is established based on a three-stage model, and the expressions for the interface shear stress and axial force distribution evolution during the whole process of anchor drawing are derived theoretically. The parameters of the interface model are given through anchor pull-out tests. Then, the load transfer law and the bearing performance of the anchorage interface under different anchoring agents are calculated and analyzed. The calculation method of the ultimate bearing capacity of the anchorage interface is verified by supplementary tests, which can provide theoretical guidance for the bolt support design.
