摘　　要：针对地质构造复杂程度难以综合量化评价的现状,基于地质构造在规模、结构、形状、力学特征等具有统计意义上的自相似性,以开平煤田钱家营井田为研究区域,采用分形理论,对地质构造发育程度进行了量化研究,提出了利用分形维数对地质构造复杂程度进行定量评价的方法。应用结果表明,钱家营井田褶曲平均分形容量维值0.939 1,褶曲分形维数为东北高,中部低,西南高。断层的平均分形容量维值平均为1.454 4,断层主要集中发育在东北部。同时,利用分形方法能够得到与数学地质趋势面分析结果精度相同的研究区构造分布情况,准确度较高。In view of the current situation that it is difficult to comprehensively and quantitatively evaluate the complexity of geological structure, based on the statistical self-similarity of geological structure in terms of scale, structure, shape and mechanical characteristics, the development degree of geological structure is quantitatively studied by taking Qianjiaying Field of Kaiping Coal Field as the research area and using the fractal theory, and the fractal dimension is used to evaluate the complexity of geological structure quantitatively. The results show that the average fractal dimension value of the fold in Qianjiaying Field is 0.939 1, and the fold fractal dimension is high in the northeast, low in the middle and high in the southwest;the average fractal volume dimension of the fault is 1.454 4, and the fault mainly developed in the northeast. The fractal method can be used to obtain the structure distribution in the study area with the same accuracy as the result of mathematical geological trend surface analysis.
