This thesis investigates the influence of different factors on the shear mechanical properties of full-length grouted anchor ropes through laboratory tests, numerical simulations and theoretical analyses to reveal the interaction between anchor ropes and surrounding rock and the anchoring mechanism for jointed rock masses. Indoor anchor cable shear tests were carried out using self-designed double shear test equipment to analyze the macroscopic characteristics of anchor cable fracture and test block damage. The changes of the anchor cable axial force, shear force and shear displacement during the shear process were recorded. The effects of preload, test block strength and cable type on the shear performance of full-length grouted anchor ropes were also analyzed. The results of the numerical simulation are used to analyze the force characteristics and the interaction between the anchor cable and the surrounding rock mass. On the basis of the theoretical analysis, it is considered that the anchoring effect of the anchor cable on the misalignment of the surrounding rock is mainly divided into two parts: the lateral and axial restraint effects, revealing the inner mechanical mechanism of the anchorage of the full-length grouted anchor cable on the jointed rock body.
