Application of High-density Electrical Method in Leakage Danger Detection of Dam Abutment

摘要: 介绍了高密度电阻率法的工作原理, 分析了相比传统水坝渗漏隐患检测的优势, 在对水库的坝肩渗漏隐患检测中, 由于坝轴线和原山体正交, 使用了折线布置测线法对坝肩进行检测, 其检测结果可以准确定位坝肩的渗漏通道；并通过钻孔对部分测线结果的验证, 为后续水坝的除险加固提供指导, 为土石坝的渗漏隐患检测、评价及后续的除险加固提供了准确可靠的依据。

Abstract: This paper introduces the working principle of high density resistivity method and analyzes its advantages as compared with the traditional leakage hidden trouble detection. One test was carried out on dam shoulder leakage detection of hidden trouble for Yat-sen reservoir, which is located in Zhongshan city, Guangdong province. Due to the dam axis and the original mountain being usually orthogonal, the researchers used the broken line layout and line detection of the abutment. The detection result can accurately locate leakage passages of the dam abutment, thus providing strong support for the subsequent drilling exploration and guidance for future consolidation. The above-mentioned means can provide a reliable basis for earth and rock-fill dam leakage hidden trouble detection, its evaluation and following-up consolidation.
