评价指标的确定和量化获取是地质构造定量研究的基础性工作 ,探讨了断层构造定量评价指标的网格化剖分、地质信息的存储与提取、评价指标的统计算法。断层构造的主要量化指标包括断层条数、断层长度、断层密度、断层强度和分维值等。设计的统计算法 ,从搜索断层与网格ID之间的映射关系入手 ,统计断层经过的各结点的指标值 ,仅对断层各结点邻近的网格ID进行搜索 ,减少了搜索点个数 ,提高了计算速度和准确度
The determination of the evaluation index and the quantitative acquisition are the basic work of the quantitative study of the geological structure. The gridding division of the quantitative evaluation index of the fault structure, the storage and extraction of geological information, and the statistical algorithm of the evaluation index are discussed. The main quantitative indicators of fault structure include the number of faults, fault length, fault density, fault strength and fractal dimension. The statistical algorithm of the design starts with the mapping relationship between the search fault and the grid ID, calculates the index values of each node passing through the fault, and searches only the grid IDs adjacent to each node of the fault, reducing the number of search points , Improve the speed and accuracy of calculation
