Determination method for reflecting mechanical characteristics of embossed anchor cable after peak load

The invention discloses a determination method for reflecting mechanical characteristics of an embossed anchor cable after peak loading, and belongs to the field of roadway surrounding rock control. Comprising the following steps: creating a grid in FLAC3D; setting a grid constitutive model, material parameters and boundary conditions; anchor units are created in the grids, and anchor cables are simulated; defining four parameters of an anchor unit; defining and executing an FISH function curve; dividing the range of the anchoring performance curve after peak load obtained in the experiment into n stages; defining and executing an FISH (fluorescence in situ hybridization) function vibratation; the damped oscillation mode of the structural unit is set to be combined-local; setting a large deformation calculation mode as true; the method comprises the following steps of: recording FISH variables (Force and disp); applying a drawing speed to a node on the outermost side of the anchor unit; and loading in a time
