含水层富水性分区的无量纲与可拓层次分析法研究

Research on water-richness of aquifer division based on non-dimensional and the extensional analytical hierarchy process

针对影响含水层富水性因素的多样性,综合分析各种地质资料与水文资料,选取了单位涌水量、含水层厚度、渗透系数、取芯率和冲洗液消耗量等五个因素作为评价指标;通过无量纲方法对不同量纲的各评价指标进行无量纲处理,使其具有可加可比性,以便各种指标进行信息融合;应用可拓层次分析法分析计算得出各评价指标的权重,结合无量纲后的指标值与计算出的各指标权重建立富水性评价模型,最终划分出不同区域的富水性程度分区图。该研究对含水层富水性的准确划分及防治水具有一定的参考意义。

Aiming at the diversified influence factors of aquifer water-richness, the author took all kinds of geological data and hydrological data into consideration, and selected five influence factors the evaluation index. The indexes were treated by the dimensionless method, to carry different information fusion; EAHP was used to calculate the weight of each index, and then the risk assessment model of aquifer water-richness was established combining the non-dimensional index values with the weight of each index. Finally, the rich degree of water-richness in different regions was divided.
