基于数据增益流场法和高密度电法的堤坝渗漏探测OA

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 leak-age 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-densi-ty electric method can judge the leakage area of the dam body,so as to judge the leakage path of the dam.
