Roughness of joints is one of key factors influencing shearing property of rock joints. By use of Mandelbrot Weierstrass function, a photoelastic model including fractal structure is proposed in this paper. And different groups of experiments have been finished on a self making shearing mechanism. The results prove that roughness of joints takes relatively strong effects on the field of displacement, property of contact and shear dilatation of rock.
