摘要
为了研究古风化壳隔水性能,了解其对底板突水的影响,通过对研究区大量地质勘探资料的系统整理、统计与分析,建立了隔水性能评价指标体系,运用GIS强大的数据管理与空间分析功能,绘制了隔水性能指标专题图,采用层次分析法确定各指标的权重,应用基于GIS的信息融合型隔水性能评价方法,对研究区中奥陶统灰岩顶部开展了隔水性能的综合评价。
In order to study the water barrier performance of the ancient weathering curst, to understand its impact on the floor water inrush. Based on the systematic analysis, statistics and analysis of a large number of geological exploration data in the study area, the evaluation index system of water barrier performance was established. Using the powerful data management and spatial analysis function of GIS, the thematic map of water barrier performance index was drawn and the weights of each index were determined by AHP. Based on the GIS-based information fusion water barrier performance evaluation method, the comprehensive evaluation of the water barrier performance was carried out at the top of the Ordovician limestone in the study area.
