【摘要】 节理的粗糙性是影响岩体力学特性的重要因素。为了能够精确地控制节理面的粗糙性本文以Mandelbrot-weierstrass函数生成不同分维的分形曲线来模氦实际的粗糙节理面,制成光弹实验试样进行多组的单压和压剪实验,通过光弹条纹和接触点的变化来研究不规则的节理对于岩体变形、应力场的影响,得出了一些有益的结论。更多还原

【Abstract】 Roughness of rock joints has an imoportant influence on the mechanical behaviours of rock masses.The fractal curves with different dimensions gerenated by Mandelbrot—Weierstrass function are used to midel the actual rough joint surfaces in order to controlling the joint roughness accurately.In this paper,a series of uniaxial compression and compression—shear experiments of the synthesized rough joints are carried out by using photoelastic method.By isocromatic fringes,contact points,the effects of the rough joints on the deformation and the stress field of rock masses are explorated and some interrsting conclusions have been obtained.更多还原
