几年来,我们在通化地区为工厂、矿山、部队、院校、林业等单位勘测水源中,作了大量水文物探工作。同时在实践中利用激发极化法寻找地下水也取得了点滴经验。众所周知,利用激发极化场△V_(ВП)衰减时 S 法可以直接寻找地下水,但由于地质条件复杂,有些地区激发极化场衰减时 S 值偏低,致使 S 值异常不明显。在这种情况下,利用激发极化场△V_(ВП)衰减曲线的“锯齿状”特性寻找地下水却是有效的。依据这一特
In the past few years, we conducted a large number of hydrological and geophysical surveys in the water source survey of factories, mines, troops, institutions, forestry and other units in Tonghua. In the meantime, it has also gained some experience in using groundwater to stimulate polarization in practice. It is well-known that the S method can directly search for groundwater when utilizing the attenuation of the induced polarization field ΔV_ (ВП). However, due to the complicated geological conditions, the S value of the excited polarization field decreases slightly in some areas, resulting in an insignificant S value. In this case, finding the groundwater using the “jagged” nature of the ΔV_ (ВП) decay curve of the induced polarization field is effective. According to this special
