【Abstract】

<正>The joints without cutting through free surface frequently appear in engineering rock masses of rock slope,rock pillars and caverns.The stiffness coefficient,the cohesion,and the friction angle of joints are the significant parameters for reflecting the mechanical characteristics of joints and analyzing the stability of engineering rock masses.Based on triaxial compression test to the rock specimens containing different joints angle and stress and displacement analysis,new geometry equations of strain and displacement were established according to the conservation of energy,the analysis solutions of stiffness coefficients of joints were derived,and the cohesion and the friction angle of joints were gained by using Mohr-Coulomb strength theory.Mechanical parameters of the joints without cutting through free surface can be determined laconically by the new calculation model in this paper.
