分形理论在地质动力区划方法中的应用

Application of fractal theories in geo-dynamical division method

利用地质动力区划方法,确定了开滦矿区的区域构造形式;根据分形理论,系统地研究了开滦矿区I～IV断裂图的分形结构特征。研究结果表明,I～IV断裂图的断裂分布以及各级断裂图断裂分布之间在不同尺度下均具有统计意义上的自相似性。通过断裂模型分维值计算和分析,有助于准确地进行断裂划分并可以对所划分的断裂进行有效的检验。

In this paper, the regional construction forms in Kailuan mining area are defined by geo-dynamical division method; the fractal structure characteristics of Kailuan mining area fracture Ⅰ - Ⅳ are studied systematically based on fractal theory. The results show that different scale distribution maps of fracture Ⅰ -Ⅳ are self-similar in statistics. Calculating and analyzing the fractal dimension values will be beneficial to accurately divide the fractures and examine the divided fractures effectively.
