Abstract Structural plane is the key factor to determine the mechanical properties of rock mass. The shear strength of the structural plane of rock mass is calculated based on the principle of energy conservation and Mohr-Coulomb strength criterion，and its feasibility is verified by the laboratory direct shear test，which is compared with the structural plane strength criterion proposed by previous research. And the testing method of the shear strength of the structural plane is proposed according to the actual rock mass structure. The following concussions can be obtained by the research. (1) The shear strength of the structural plane of the rock mass can be calculated by using the principle of energy conservation and Mohr-Coulomb strength criterion. (2) The morphological characteristics of the structural plane have an important influence on its shear strength，which is mainly manifested as the undulation degree，undulation angle，roughness and the proportion of the raised part. In the two-dimensional condition，the length is taken as the measurement standard，and in the three-dimensional condition，the proportion of the concave and convex region in the area should be considered. (3) The shear strength can be calculated indirectly and simply by measuring the morphological of the structural plane and the strength parameters of the structural plane wall.

Key words： rock mechanics energy conservation structural plane shear strength strength criterion
