摘　　要：水库大坝内薄弱部位由于库水长期浸泡,在坝体内形成含水丰富的浸润体,构成水库大坝的隐患,对大坝安全构成严重威胁,利用坝体浸润体含水越多,其电阻率越低特征,采用高密度电阻率法技术,根据低阻异常圈定含水丰富的浸润体,从而确定水库大坝内隐患部位。本文介绍高密度电阻率法探测技术方法,根据实例应用,进行成果分析,取得有效成果。The weak position inside a reservoir dam may form a water-rich infiltration body in it due to the reservoir water soak for a long time, posing a great threat to the safety of the dam. Based on the fact that the more water it contains, the lower resistivity it shows, we delineated water-rich infiltration bodies using high-density resistivity method. This paper introduces the detection technology of high-density resistivity method, analyzes the results according to the practical application, and obtains effective results.
