The invention discloses a method for testing the binding force of an anchoring agent and rock interfaces. The method comprises the following steps: (a) according to international rock mechanics testing standards, manufacturing a cylindrical rock sample; (b) according to the specification of the cylindrical rock sample and anchoring parameters of the anchoring agent, designing an Acrylic pipe annular die and a cutting sleeve matched with the Acrylic pipe annular die; (c) manufacturing a rock-anchoring agent assembly by using the designed Acrylic pipe annular die; (d) enabling the well designed cutting sleeve to be mounted on a rock mechanics servo testing machine, applying loads to the surface of the anchoring agent of the rock-anchoring agent assembly through the sleeve by the rock mechanics servo testing machine, and performing cutting tests; (e) enabling a master control computer to be connected with the rock mechanics servo testing machine, and performing data collection so as to obtain the binding force of the anchoring agent and the rocks. According to the method disclosed by the invention, the problem that the binding force of the anchoring agent and the rock interfaces is difficult to test is solved, and an experiment foundation is provided for the analysis of influence of the drilling enclosing rock conditions on the anchoring effect in an anchor bolt support technique in the engineering field.
