示踪技术和水化学分析在水库渗漏勘察中的综合应用

Comprehensive Application of Tracer Technique and Hydrochemical Analysis in Reservoir Leakage Investigation

渗漏是水工建筑中最为常见的老化病害之一,准确快捷的查找到渗漏源及渗漏通道是解决渗漏问题的关键环节。该文以某水库大坝为例,针对多年来左坝渗漏存在的问题,应用了水化学分析以及一系列基于示踪技术的手段,确定了左坝廊道内异常涌水的渗漏源。示踪连通试验相互印证、互为补充确定了渗漏途径为坝体渗漏。该文采用多种方法综合应用,为以后水库渗漏勘察提供新的视角,为多学科在水库勘察中的结合与交叉应用提供了案例。

Leakage is one of the commonest aged disaster of hydraulic architecture . The way to find leak- age source and leakage passage accurately and quickly is the key link to solve the problem of leakage. In this paper, taking a reservoir dam as an example, aiming at the leakage problem in left dam, using the hydrochemical analysing and a series of means based on tracer technique, the leakage source of abnormal water inrush in left dam corridor is determined. The leakage path is identified as dam seepage by the trac- ing and connective experiment confirming and complements for each other. In this paper, various meth- ods are applied comprehensively to provide new visual angel for reservoir leakage investigation in future, and it provide a case for combination and cross the application of multi discipline in reservoir exploration.
