摘要
为查明于桥水库大坝渗漏隐患区域及其成因,采用高密度电法分别探测了0+356、1+130、1+605三个断面两侧93m范围内的坝体视电阻率分布情况.探测结果表明,三个断面附近均存在低视电阻率体,为渗漏隐患区域,探测结果与坝体渗流压力监测资料分析成果基本一致,验证了高密度电法的可靠性.
In order to find out the Yuqiao reservoir dam leakage area and its causes,using high density resistivity method detecting the resistivity distribution in the 93 m range of three sections of 0 ＋ 356,1 ＋ 130 and 1 ＋ 605. The results show that the low resistivity bodies exist near the three sections are leakage zones. The detection results and the analysis results of dam seepage pressure monitoring data are basically consistent,verify the reliability of the high density resistivity method.
