摘要 岩体节理粗糙度JRC不但是估算节理抗剪强度和变形指标最重要的参数,而且对于研究岩石的剪胀效应和渗流性质等具有重要意义.笔者主要回顾了近年来国内外对岩石节理粗糙度系数(JRC)研究的进展,以及所取得的成果,尤其将分形理论应用于研究岩石节理的粗糙度以后,使得对岩体节理粗糙度的描述取得了一定的发展,并得出了JRC与维数的一系列的关系. Joint roughness coefficient is not only the most important factor in evaluation of the shear strength and deformation parameters of rock joints, but also a more important siqnificance in research into the permeability and the dilatational effects of the rock. The recent developments and effects made at home and abroad are studied in this paper. There is a great progress to make in researching JRC, especially applying the fractal to this field .
