The large-scale model test bench frame is adopted to carry out shear test on the pre-stressed anchor block containing structural plane, and the characteristics of tensile, bending and shear failure of anchor cable are analyzed. Furthermore, the structural calculation software ABAQUS 2020 is utilized to construct the spiral structure model of composite steel wires and the anchor cable is simplified to be composed of bending inner and outer steel wires and central steel wire, so as to simulate accurately the interaction, failure mode and mechanical mechanism between anchor cable and grouting bod...
