摘　　要：基于岩体结构面表面形态的各质异性、各向异性、非均一性和尺寸效应，本文提出粗糙度系数（JRC）的统计估测方法．根据11064条表面轮廓曲线的测量统计资料，提供16种典型岩体结构面3个方向的粗糙度系数经验值．本文的JRC经验值可直接用于岩体结构面的力学参数估算．On the basis of nonuniformity, anisotropy, anisotropism and scale effect of surface profiles of rock joint, we present the statistical eshmating method of joint roughness coeffifcient (JRC). According to statistical measuring value obtained by 11064 surface profiles of rock joints, we put forward the JRC reference value on 3 directions of 16 rockes. This JRC reference value can directly estimate mechanical parameteres of rock joints.
