Introduce the cohesion-friction model of rock strength theory, and extend the model to select the strength of sliding plane, discuss the variation rules of peak strength and residual strength under different normal stress, and then present the selection model of shearing strength. After the result of cohesion-friction model is compared with Coulomb Criterion, it is found that when the results of shearing strength are many and adjacent the strength parameters can not be regressed by least square method, instead the results should be divided into some beelines at that time according to the cohesion-friction model.(4) Discuss the characters of hard structural plane and weak structural plane: The adhesive friction theory is applied to research the changing course of shear area of hard structural plane and its influence on shear stress.
