The bolt anchorage performance with shear force has been analysed by analytical method in this paper. By coding in Matlab, the loop and the judgment statement can be used to control the displacement angle. The force-displacement curve of the analysis model from the beginning of loading to the failure of the bolt under a certain displacement loading angle is obtained. In the test and field, the values of displacement and force before failure and the load-displacement curves before the peak value can be obtained by using the program with the parameters. The bolt deformation in different strength surrounding rock mass and the anchoring influence of the rock bolt with different diameters have been studied. The resultant displacement increases linearly with the increase of the bolt, and the resultant force increases exponentially with the increase of the bolt.
