摘　　要：本文首次提出了断裂粗糙度系数的各向异性和粗糙度系数尺寸效应的各向异性概念。根据不同成因断裂表面形态的定性分析结果,结合2180个不同方向粗糙度系数实测值的统计结果,系统地阐述了Ⅰ型断裂(节理)和Ⅱ、Ⅲ型断裂(断层)粗糙度系数及粗糙度系数尺寸效应的各向异性规律。In this paper a new conception on the anisotropy of joint roughness coefficient and its size effect are put forward. From the result of qualitative analysis of fault surface morphology of various genesis in connection with the statistical result of 2180 measured joint roughness coefficient values in different directions, We describe the anisotropy of roughness coefficients of joint I and fault II and III and their size effect.
