Abstract: On the base which the roughness profile is model as a series of irregular shaped, triangular asperities, the shear failure mechanism of tooth-shaped joints was studied. The shear strength equation was derived, in which the surface profile of joints were considered.The relationship between equivalent cohesion and joints cohesion was established. The equivalent coefficient was proposed and the rule of the coefficient was studied. By discussing the equation under low, medium, high normal stress, some conclusions were drawn.

Key words: application, joints, equivalent fiction, equivalent cohesion, equivalent coefficient
