基于有效度的模糊综合评判法在含水层富水性评价中的应用

为了对目标含水层进行富水性评价、解决以往评价方法不能进行合理分区的问题，在充分利用矿井地质、水文地质资料的基础上，建立了以单位涌水量、渗透系数、含水层厚度、岩芯采取率、脆塑性岩厚度比等5个指标为主控因素的含水层富水性评价指标体系，应用基于最大隶属度原则的模糊综合评判法，对含水层进行富水性评价分区。引入有效度理论，检验最大隶属度原则评价结果的有效性，对不可信区域采用加权平均原则进行重新评价，最终确定全区富水性评价结果。结果表明，基于有效度的模糊综合评判法对含水层进行富水性评价是可行的，为含水层富水性评价提供了一种新的方法。

Application of Fuzzy Comprehensive Evaluation Method based on Validity in Water Abundance Evaluation for Aquifer

In order to evaluate the water abundance of the target aquifer and solve the problem that previous evaluation methods can not effectively reflect water abundance zoning.On the basis of making full use of geological and hydrogeological data,a water abundance evaluation index system of aquifer was established,which was mainly controlled by five indexes,namely,unit inflow,permeability coefficient,thickness of aquifer,core recovery and thickness ratio of brittle plastic rocks.The fuzzy comprehensive evaluation method based on maximum subordination principle was applied to perform water abundance evaluation zoning of aquifer.The theory of degree of validity was introduced to test the validity of the evaluation result of maximum subordination principle,the weighted average principle was adopted to reevaluate the untrusted region,and finally the evaluation result of water abundance in the whole region was determined.The results show that the fuzzy comprehensive evaluation method based on validity is feasible to evaluate the water abundance of aquifer,and it provides a new method for the water abundance evaluation.
