摘　　要：结合工程实例,分析了高密度电阻率法不同探测装置的适用性,对电极距、扫描层数等参数设置进行了探讨,经过比较斯隆贝格装置和温纳装置0.5m、1m、2m三种极距,6层、8层、12层、16层扫描层数等多种组合,在子牙新河堤防探测中制定了采用斯隆贝格装置、2m极距、8层扫描的探测方案。通过开挖探坑及土工试验,提出了筑堤土料黏粒含量与含水率呈线性关系,含水率与视电阻率呈指数关系,并针对具体工程制定了隐患判别的原则,对子牙新河232km堤防进行了探测并判别出工程可能存在隐患。Combined with the engineering cases the applicability of different detection devices of high density resistivity method are studied. The parameter settings of electrode distance, scanning layers are discussed. Through the excavation of test pit and soil test, the relationship between embankment material clay content and apparent resistivity is proposed. And the principles of hidden trouble distinguishing to the specific projects are formulated.
