摘　　要：高密度电法是一种经济、高效、精确的物探方法,在解决含水性地质病害问题时具有明显的优越性。本文简要介绍了高密度电法的基本原理和资料处理,将高密度电法应用于某隧道的勘查工作中,结合测区的地质资料和地球物理特征,推断隧道所经区域内含水病害的分布情况及覆盖层的厚度,并通过钻孔验证了推断成果,为后期隧道工程建设提供了地球物理勘探资料。The high density resistivity method is an economical, efficient and accurate geophysical method which has obvious advantages in solving the problem of water-beating areas. This article briefly introduces the basic principles and the data processing of high density resistivity. The high density resistivity was applied to tunnel exploration. Combined with the geological data and geophysical characteristics of the surveyed area, we can infer the distribution of the water-bearing areas and the thickness of the overburden in the tunnel areas. The result was confirmed by drilling data and it can provide geophysical data for the later tunnel construction.
