高密度电阻率法与常规电阻率法原理基本一致,之所以称为高密度,是因为在电法测量时,测点排列的相当密。文章通过在贵州某河流地区实测的高密度剖面,介绍了高密度电法在砂卵石覆盖层勘察中的应用效果。 High-density resistivity method and conventional resistivity method is basically the same principle, called the reason for the high density, because in the measurement of electrical method, the measuring point arrangement is quite dense. This paper introduces the application of high density electrical method in the investigation of sand and pebble covering through the high density section measured in a river area in Guizhou.
