| 摘 要： | 节理的粗糙性是影响岩石节理剪切力学特性的重要因素。本文以Mandelbrot-Weierstrass函数构造具有分形结构的光测力学模型，在自制的压剪实验装置上进行不同组别的压剪实验，试验结果表明：节理的粗糙性对其位移场、接触特性和剪胀特性均有较大的影响。

| Abstract: | 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. |
