摘 要:在明确堤坝介质所具有的地球物理前提的基础上,利用电阻率法区分堤坝中不同性质的隐患,确定引起堤坝渗漏的地质原因和坝体内隐患的存在部位.通常隐患处介质和非隐患处介质电性差异不大,为提 高电阻率法的探测效果,采用反射系数K法对ρs 资料进行解释,能进一步提高堤坝隐患探测的分辨能力,为堤坝隐患的治理提供可靠的地质依据,从而开拓了电阻率法的应用领域,为防洪减灾提供科学依据
Abstract: Resistivity method is used to explore the different hidden danger and find out the position and geological reason of seepage in embankment. It improves the distinguishing ability in surveying the hidden danger in embankment, and gives a reliable foundations of geology to harness the hidden danger in embankment.
