摘　　要：堤坝渗漏是影响水利工程安全运行的主要因素之一,因此对堤坝进行渗漏探测十分必要。为应对多种物探方法在堤坝渗漏探测中均容易出现小渗漏点漏检与误判的问题,研究通过数据增益流场法结合高密度电法对坝体渗漏进行探测。结果表明:数据增益的流场法可以突出小异常值数据敏感性从而提高探测精度,多条测线的异常曲线特征能更精准判断渗漏入渗点;高密度电法的低视电阻率区域可判断坝体渗漏区域,从而判断大坝渗漏路径。Dike leakage is one of the main factors affecting the safe and stable operation of water conservancy projects,and is very important for dike leakage detection.To address the issue of small leakage points being missed or misjudged in dike leakage detection using various geophysical methods,this study explored the use of the data gain flow field method combined with the high-density electrical method for detecting leakage in the dam body.The results showed that the flow field method of data gain could highlight the sensitivity of small outlier data and improved the detection accuracy,the anomaly curve characteristics of multiple survey lines can more accurately judge the leakage inlet point,and the low-visual resistivity area of the high-density electric method can judge the leakage area of the dam body,so as to judge the leakage path of the dam.
