Abstract The surface of joint specimen has been scanned by using 3D surface profiler Talysurf CLI 2000 and the surface shape is numerical expressed in order to implement the 3D visualization of joint surface. Then，after the analysis of 3D surface topography characteristics with fractal geometric theory，the function，connected with fractal dimension and JRC of joint profile，is put forward. By taking a single joint surface as the research object，this paper probes into the relation between the fractal dimension of joint profile，JRC and the fractal dimension of joint surface，which has important significance in introducing fractal geometric theory to research the joint surface state.

Key words： rock mechanics joint three-dimensional topography profile fractal dimension
