摘要: 本文给出了６种节理的分形量测方法，讨论了岩石节理粗糙性的分形描述，ＪＲＣ和分形维数的关系，以及分维对节理抗剪强度和节理摩擦角的影响。可以说，分维能定量地刻画节理的粗糙性，并有可能用来预测节理抗剪强度和节理摩擦角。

Abstract: In this paper,six methods of fractal dimension measurements for a joint are given.Fractal descriptionof the joint asperity,relationship between JRC and fractal dimension,and the effect of fractal dimension on shearstrength and friction angle of joints are discussed.Fractal dimension can be used to quantitatively describe jointroughbness and to and to estimate strength and friction angle of joint.
