在水文地质勘探中,目前广泛应用的是电阻率法。在1958年大跃进的年月里,山西省水利战线的同志们大搞电阻率法找水的群众运动。十多年来,配合钻机确定井位,对抗旱打井作出了较大的贡献。但是,任何方法都不是万能的,电阻率法也是有其局限性的。由于它的分析计算方法是在地层都是水平成层、各相同性、无限延伸的前提下得出来的,所以在沟谷纵横、山峦起伏的丘陵山区应用就很困难。这是因为在这种情况下,地形引起的视电阻率异常,比因地层的导电性引起的异常要大。此外,对于象岩溶溶洞水等小泉小水和埋藏较深的薄含水层,电阻率法反映也不明显。
In hydrogeological exploration, the current widely used resistivity method. In the years of the Great Leap Forward in 1958, comrades from the water front in Shanxi Province devoted themselves to the mass movement that used the resistivity law to find water. More than a decade, with drilling rig to determine the well position, made a greater contribution to the fight against drought drought. However, any method is not a panacea, the resistivity method also has its limitations. Because of its analysis and calculation methods are stratified stratification, the same nature, unlimited extension of the premise, so vertical and horizontal valleys, rolling hills and hills in the application is very difficult. This is because in this case, the apparent resistivity anomaly caused by the terrain is larger than that caused by the conductivity of the formation. In addition, the resistivity method is not obvious for small water such as karst karst cave water and buried deep aquifer.
