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- Weier-strass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
The roughness of joints is an important factor that affects the shear mechanics characteristics of rock joints. In this paper, an optical mechanics model with fractal structure was constructed by Mandelbrot-Weier-strass function. Different groups of compression-shear experiments The experimental results show that the roughness of joints has a great influence on the displacement field, contact characteristics and dilatancy characteristics
