摘要
潜水防污性能可以用包气带粘性土层厚度、包气带厚度、含水层富水性和含水层纳污指数等4项评价因子来描述,并将潜水防污性能划分为3级,进而用模糊数学方法对这4项评价因子逐项进行分析,提出了不同评价因子对不同防污性能级别的隶属函数,由统一基本权值和附加权值得到各评价因子的实际权值。在单因素模糊评价的基础上进行综合评价。最后以一实例加以说明。
In the paper, the capability of antipollution is described with four factors which are thickness of clay layer of aeration zone , thickness of aeration zone, capability of aquifer and exponent of adsorption in aquifer and the capability of antipollution of phreatic aquifer is divided into three grades. The four assessment factors are analyzed one by one with fuzzy mathematics methods, was put forward subjected function with different appraised factor for different grade of antipollution capability, the actual value is gained with uniform basic weighed value and additive weighed value. And the general evaluation was made based on single factor fuzzy evaluation. At last an example was taken for illumination.
