为对裂隙含水层的富水性进行科学合理的评价,以马营堡井田为例,以断层分形维数表征含水层裂隙的发育程度为评价含水层富水性的一项主控因素;在分析确定其它富水性主控因素的基础上,采用加权灰色关联度评价方法,以指标关联度作为因素权重,以方案关联系数作为判断矩阵,加权灰色关联度即可表征含水层富水性强度,建立了富水性强度与地理坐标的对应关系并运用GIS生成富水性分区图.单位涌水量并未作为富水性的一项主控因素,而是作为含水层富水性的实测指标对该法的评价结果进行验证,结果表明:将断层分形研究方法与灰色关联度方法相结合运用于裂隙含水层的富水性评价具有较高的准确性和客观性,可为其它地区特别是水文地质资料较为缺乏地区的富水性评价提供理论参考.
In order to evaluate the water-bearing capacity of fractured aquifers scientifically and reasonably, taking Ma Ying Bao minefield as an example, the fractal dimension of fractures is used to characterize the development degree of aquifer fractures as a major controlling factor for evaluating the water-bearing capacity of aquifers. After analyzing and confirming Based on other main control factors of water-richness, using the method of weighted gray relational assessment, taking the indicator correlation degree as the factor weight and the program correlation coefficient as the judgment matrix, the weighted gray relational degree can be used to characterize the water- Water intensity and geographical coordinates of the corresponding relationship and the use of GIS to generate water-rich zoning map unit inflow is not as a water-rich main controlling factor, but as a measure of water-rich aquifer indicators to verify the evaluation results The results show that the combination of fractal fractal method and gray relational degree method is of high accuracy and objectivity for the evaluation of water-bearing capacity of fractured aquifers. It can be used for the evaluation of water-rich in other areas, especially in areas where hydrogeological data are scarce Evaluation provides a theoretical reference.
