An analysis of the source and distribution of SO42- in dam site area of the Wudongde Hydroelectric Station on Jinshajiang River

摘要: 针对金沙江乌东德水电站坝址区左右两岸地下水中SO42-含量的差异,尤其是左岸SO24-含量普遍高于右岸的特征,通过岩矿和水化学成分分析,采用聚类分析法分析了地下水中SO42-与其他离子成分的相关性,并结合水岩相互作用及水化学场、水温场、水动力场等方面的分析研究,发现坝址区地下水中SO42-的来源主要与地层中的黄铁矿有关,左右两岸地下水中SO42-含量的差异主要由于二岸地下水循环不同所致。Abstract: Difference in SO2-4 contents exists in groundwater in two banks of the Wudongde Hydro-electric Station.In particular,the SO2-4 contents in left side is generally higher than those in the right side.Combined with the study of water-rock interaction,hydrochemical data,temperature and hydrodynamic data,the characteristics of rock and mineral and hydrochemistry were analyzed.The cluster analysis was used to search the relativity of SO2-4 and other ions.It is found ultimately that the source of SO2-4...
