金沙江某水电站坝址区水化学特征研究

Research on Water Chemical Characteristics in the Dam Area of a Hydropower Station of Jinsha River

为解决开发大西南水能遇到的最大问题岩溶渗漏,以云南省金沙江某水电站为例,应用区域水文地球化学理论,分析了其坝址区水化学特征。结果表明,该区地表水与地下水化学特征比较类似,为判定大区域内岩溶系统是否属于同一流动系统,解决岩溶渗漏问题提供了可靠的基础地质资料。

To resolve the biggest problem with the development of water in the Southwest area - Karst leakage, a hydropower station of Jinsha fiver in Yunnan province was took as an example, the chemical characteristics of water in the dam area was analysed using regional hydrogeochemieal theory. The result can find whether the large area of Karst systems belong to the same vadose cave system, which provides the reliable geological data for the study of Karst leakage problems.
