摘　　要：以巴顿提出的10条典型粗糙度剖面模型为基础,从立体学和形态数学原理出发,讨论巴顿模型的线粗糙度和面粗糙度特征及其分数维特征;并通过一些学者研究成果的比较,对巴顿模型进行了一定的探讨,得出了结构面的抗剪强度不仅与裂隙粗糙度系数或分数维有联系,而且还与岩性特征有关的结论.The characteristics of linear rugosity, areal rugosity, and fractal dimension related to the JRC were discussed based on Barton's models of 10 typical profiles and the principle of stereology and morphological mathematics. By a comparison with some experts' researches, the theoretical basis of Barton' models was further discussed, and it is concluded that the shear strength of the structural surface is not only related to the roughness coefficient or fractal dimension of joints, but also related to the characteristics of rock mass.
