摘要
文章论述了四川冶勒电站库区内河水、泉水、承压水的同位素组成特征,讨论了泉水、承压水的补径排关系,确认了库区内河水和各层承压水之间不存在直接的水力联系,排除了河水向下渗漏的可能性。
This paper deals with the isotope composition feature of the river, spring and confined waters in the reservoir of the Yele power station, Sichuan, and discusses the relationship among therecharge, run off and discharge in the spring and confined waters. And it is found that there is not thedirect hydraulic connection between the river and confined waters in the reservoir area and the possibil-ity of the river water down-leakage may be eliminated. The study indicates that the isotope techniqueprovided a new and available approach for resolving complex hydrogeologic problems.
