摘要
当利用自然电位法（ＳＰ法）在火山岩地区勘探地下水时，发现负的自电异常大小与地下非饱和区厚度之间存在一个线性关系．从理论上对该经验关系进行探讨，并提出针对这一水文地质问题的自电测量解释方法．
When the self-potential(SP) method is applied to hydrogeological exploration in volcanic areas,there is a linear correlation between the range of negative SP anomalies and the thickness of the unsaturated zone measured in boreholes. In this paper,this linear correlation is theoretically studied. Then from this relation,an interpretative method of self-potential measurements is developed for the hydrogelogical exploration in volcanic areas. Finally,the exploration result in the Chaine des Puys (France) is presented.
