开发大西南水能首先遇到的最大问题是岩溶渗漏 ,特别是对巨型水电站来说 ,大范围区域性岩溶渗漏研究其钻探工作难度大 ,基础地质资料匮乏。本文结合川西南某水电站实际 ,提出应用区域水文地球化学理论 ,分析水化学成分信息 ,对解决这类渗漏问题达到了节约资金 ,又能克服研究范围广、地形险恶、资料极少 ,水文地质周期长等难点。结果显示该方法是研究岩溶区域渗漏问题的一种简单、有效方法之一 ,与其他方法联合运用 ,达到了极佳的效果
The biggest problem that can be encountered first in the development of the SWS is karst leakage. Especially for giant hydropower stations, large-scale regional karst leakage research is difficult and difficult to drill, and the basic geological data are scarce. Based on the actual situation of a hydropower station in southwest Sichuan Province, this paper puts forward the application of regional hydrogeochemistry theory to analyze the information of chemical composition of water, and saves the funds to solve such seepage problems. It can also overcome the problems of wide range of research, dangerous terrain, little data, Long cycle and other difficulties. The results show that this method is one of the simple and effective methods to study the leakage problem in karst areas, which is combined with other methods to achieve excellent results
