裂缝的分形分析方法

从裂缝的分形分布出发,对裂缝的分布、裂缝的有效截面积、裂缝的强度、裂面的粗糙度和裂缝的各向异性度,提出了分形分析方法。根据裂缝分形分布特点,提出了基本裂缝分布模型,对这些模型做相应的分形对比,来阐明裂缝的分形和特征。裂缝的分形分析方法改变了以往单一的裂缝性质分析方法,而从裂缝的分形分布结构上全面地进行定量分析,不仅反映裂缝的平均效果,而且反映了裂缝分布的非均匀性及其发育程度的差异。

FRACTAL ANALYSIS OF FRACTURES

Based on the fractal distribution of fractures, the paper proposes the methods of fractal analysis for the distribution, the valid cross section, the intensity of fractures, the coarse intensity of fracture face and the anisotropy of fractures in rock. Based on the basic models of fractal distribution of fractures proposed in the paper, the fractal properties of fractures are compared and analysed. By the methods of fractal analysis for the fractures, the fractures can be analysed quantilitiely in the fractal distribution of fracture structure, which is different from the traditional method only studying single property of fractures. The fractal methods of fractures not only reveal the average effect of fractures, but also reveal the anisotropy and intensity of fractures.
