摘要
通过对川西南某水电工程坝址上、下游几十公里范围内下二叠统（Ｐ１）地层中岩溶水水化学场特征的分析研究和对比，运用反证法判定，区内该层中的岩溶水，虽然处在同一个含水系统中，但并非属同一个流动系统，进而论证了在不蓄水情况下不存在库区、坝区地下水沿Ｐ１灰岩向金沙江下游渗流问题。结果显示，利用水化学成分信息判定坝址上、下游岩溶水是否属同一个流动系统，进而分析渗漏可能性是一种简单、可靠的方法。
By analysis and comparison of hydrochemical field characteristics to the karst water in the strata P 1 about tens of kilimeters on the upper and lower reaches of certain hydropower project damsite in Southwestern Sichuan,using reduction to absurdity shows that though the karst water is in a same water bearing system,the flow systems are different.Furthermore,it is also demonstrated that the groundwater of reservoir and dam region doesn′t seep along P 1 limestone towards the lower reach of the Jinsha River in the case of no storing water.The result shows that the method,taking advantage of hydrochemical data to determine whether the karst water of the upper and lower reaches of the damsite is in a same flow system and to analyse the likelihood of karst leakage, is simple and reliable.
