摘要
在论述了采用水文地球化学方法探查坝基帷幕体防渗缺陷的基本原理的基础上 ,结合数个工程实例的应用 ,认为该方法是有效的、可行的。并指出 ,该方法的有效性在很大程度上取决于水化学分析资料的精度。最后 ,也对如何提高其精度作了扼要的讨论。
In this paper, the principles of locating the anti leakage deficiency of curtain grouting under a dam foundation with the hydrogeochemistrical method are introduced. Application to several projects shows that this method is effective and feasible. It is pointed out that the effectiveness of this method depends largely on the accuracy of water chemistry data. Finally, the way to improve its accuracy is discussed.
