| 摘 要： | 利用环境同位素方法对高水河堤防几个典型段进行了渗漏分析,查明了其地下水的渗漏来源,结果表明,江都船厂段T1#孔、小菜谭段T23#孔中的地下水为河水补给来源,T5#孔附近的黑鱼塘水为当地降雨补给,万寿宫段T7#孔中的地下水为河水和当地降雨的混合。由于环境同位素的分析方法只能定性的说明问题,笔者尝试应用模糊聚类方法,选取环境同位素和水化学值作为指标特征值,并赋与不同的权重,进行模糊聚类分析,分析结果与环境同位素、水化学分析结论一致。

| Abstract: | The leakage problems of several typical sections of Gaoshuihe embankment are studied by applying the environmental isotopes method in the paper.The leakage sources of groundwater are ascertained.The result shows that the groundwater of T1~# borehole at Jiangdu dockyard and T23~# borehole at Xiaocaitan section is recharged by the river water,the water of Heiyutang around T5~# borehole is recharged by the local precipitation,and the groundwater of T7~# borehole at Wanshougong section is the mixing of river water and local precipitation.Because the environmental isotopes method can only qualitatively explain the problem,the paper attempts to perform quantitative analysis of fuzzy clustering by applying the fuzzy clustering method that the environmental isotope and the hydrochemistry values are taken as the index characteristic values and endued different weightings.The analysis result is according to the conclusion judged by environmental isotope and the hydrochemistry. |
