摘要
岩石节理是影响工程岩体稳定性的主要因素之一。岩石节理力学行为研究一直是岩石力学界广泛关注的课题。本文总结了分形理论用于岩石节理力学行为研究的研究进展,主要内容包括:(1)岩石节理表面几何形态的分形描述,介绍岩石节理的理论分形模型以及岩石节理表面粗糙度的直接分形量测;(2)岩石节理力学行为的分形研究,介绍分形节理接触力学的光弹实验研究,岩石节理表面粗糙度在载荷作用下的演化规律及其力学性质的实验分析研究,断层面分形效应的物理模拟研究等。
Rock joint is one of the major factors which affects the stability of engineering rocks. In past decades, extensive efforts have been devoted to the study of the mechanical behaviors of rock joints. In this paper, the applications of fractal geometry to study of mechanical behavior of rock joints are reviewed. Applications of fractal in this area can be grouped into two categories: (1) fractal description of morphology of rough surface of rock joints; (2) fractal study of mechanical behaviors of rock joints. The photoelastic study of contact mechanics of fractal rock joints, the experiments of the evolution of roughness and mechanical behavior of rock joints under applied loads and the physical model experiments of fractal effects of fault are mainly introduced.
