运用分形理论对鄂西恩施、建始断裂的几何分形结构特征进行了研究，并选取有代表性的碎裂岩作了粒径—频度分析，表明其同样具有分形结构，分维值可以定量地反映恩施、建始断裂同为地壳上部浅层构造，几何结构较为简单，构造活动性弱，分别趋于构造衰亡和发育成熟阶段。在这两条断裂附近通过水系的分形统计结果分析，断裂几何分维值的意义与其最后一次活动表现出的水系切错和同步弯曲现象相吻合。分维值可以作为断裂工程活动性评价的一个定量指标。
The fractal theory is used to study the geometric fractal features of Enshi and Jianshi faults in western Hubei Province. The representative fractured rocks are selected to make the particle size-frequency analysis, which shows that they also have the fractal structure. The fractal dimension can be quantitatively reflected Enshi and Jianshi faults are the same as the shallow crustal structures in the upper crust. Their geometrical structures are relatively simple and their tectonic activities are weak. They tend to be in the stage of decline and maturity. The analysis of the fractal statistical results of the water system near the two faults shows that the significance of fractal fractal dimension coincides with the phenomenon of water system cutting-off and synchronic bending exhibited by the last activity. The fractal dimension value can be used as a quantitative index of fracture engineering activity evaluation.
