| 摘 要： | 节理的粗糙性是影响节理力学性质的重要因素。本文以分形曲线模拟岩石节理的粗糙特征,并应用数值模拟的方法对岩石节理在单压状态下粗糙节理的最大剪应力、最大剪应变及其接触点分布情况进行较为系统的研究。本文的模拟结果和实验结果吻合较好。

| Abstract: | Roughness of rock joints is a major factor affecting mechanical properties of rock joints. In this paper, the rough characteristics of natural rock joints are simulated by several fractural profiles. The maximum shear stress, the maximum shear strain and contact points distribution state of rough joint under uniaxial compression are systematically analyzed using numerical simulation. The results of numerical simulation show identical views in contrast to experimental results. |
