岩溶管道的发育是水利水电工程的重大安全隐患,所以查清渗漏管道的存在与否是岩溶区水利水电工程的一项重要的基础性工作。示踪方法在检测渗漏通道存在性方面占有着特殊的地位, 因为这种方法能够证实各试验点连通关系并且直接了解地下水运动的过程。本文就是通过示踪试验对西部地区某一水电站左坝肩的进行调查研究,最终确定各试验点之间存在渗漏通道。

[Abstract]
The development of Karst seepage channel is a major safety hazard to the hydropower projects, and therefore the identification of the presence or absence of seepage channel in the water conservancy and hydropower project is an important work. Tracer method is a popular method in terms of detecting the existence of seepage channel , because this method can detect the connection between each test points and then determine the process of groundwater movement. In this paper, tracer test was applied in the left abutment of a hydropower station in Western China, which detected the presence of seepage channel between each test points.
