基于温度电导示踪的渗漏探测在仁宗海水库大坝右岸的应用

Application of Leakage Detection Based on Temperature Conductivity Tracer in the Right Bank of Renzonghai Dam

仁宗海水库大坝自蓄水以来,一直存在较为严重的渗漏问题,四川川投田湾河开发有限责任公司曾多次开展渗漏检测和治理,但大坝右岸渗漏治理效果始终不明显。为彻底探明大坝右岸渗漏问题,采用行业内较为先进的温度电导示踪技术,根据水库蓄水情况,分三个阶段对右岸进行了较为全面的探测,并结合右岸监测数据对比分析,基本确定大坝右岸存在集中渗漏通道。同时,通过对温度电导数据的详细分析,也确定了渗漏通道所在高程的区间范围。

Since the impoundment of Renzonghai Reservoir,there has been a serious leakage problem.Sichuan Chuantou Tianwanhe Development Co.,Ltd.conducted multiple leakage detection and treatments,but the leakage treatments on the right bank of the dam were not effective.In order to thoroughly investigate the leakage problem on the right bank of the dam,an advanced temperature conductivity tracing technology was used.Based on the water storage situation of the reservoir,a comprehensive detection was conducted on the right bank at three stages.Combined with comparative analysis of monitoring data on the right bank,it was basically determined that there was a concentrated leakage on the right bank of the dam.At the same time,through elaborate analysis of temperature conductivity data,the range of elevation of the leakage channel was basically determined.
