Abstract
The anisotropy, scale effect and interval effect are main characteristics of rock mass structure plane roughness. Based on the 3D laser scanning data and supplemented by the data generated by a random fractal function, the influential factors for rock mass structural plane roughness is analyzed from the 2D and 3D perspective respectively. The results show that visual judgment error of structural plane from different sampling directions is large, thus the quantitative judgment is necessary. With increase of sampling size, the structural plane roughness decreases, and the roughness tends to be stable when the sampling size reaches to an effective size;with the decrease of sampling interval, the structural plane roughness increases, and the roughness increases slowly and tends to be stable when the sampling interval reduces to an effective interval. When the sampling interval is too large, no fractal characteristics would exist.关键词
