self-potential method
2 iran dianchangfa自然电场法(self一potential method)观测、研究地下介质中在天然条件下形成的动电学电位和静止自然电位分布规律的工程电法勘探方法。在工程勘寨中,研究自然电场的成因,主要是由不同浓度的溶液通过毛细管或多孔介质形成的和各种离子迁移率差异引起的电位差。其他由金属或金属氧化物引起的能脱斯电位、矿化电位、氧化还原电位等都是干扰因素,必须分辨清楚,并加以排除或压制。 自然电场法的野外工作方法有电位法和梯度法两种。电位法是观测某点相对于某一固定基点(位于正常场)的电位值;梯度法是观测同一测线上相邻两测点之间的电位差。在供水水文地质勘察中,常用梯度法的变种—“8"字形法(又称环形法)来确定地下水流向。自然电场法可用于:确定水库的漏水位置,了解地表水与地下水的水力联系,探测岩溶和滑坡面的发育位置,研究抽水试验下降漏斗的影响半径等。如何识别真假异常和压制干扰,是巫待解决的难题。自然电场法使用的仪器有电位计、不极化电极等。 (范昌隆)
