摘要
介绍了利用电法在非洲尼日利亚火成岩地区勘察地下水的应用实例,总结出该地区地下水赋存的电测深曲线特征:电阻率曲线尾支呈45°上升,转折点对应的AB/2≥38 m;电阻率曲线转折点<38 m,但有极化率异常。
This paper describes the electrical prospecting work for groundwater water in the igneous rock area of Nigeria, Africa, and summarizes characteristics of electrical sounding curves of groundwater in that area. It is shown that the branch tailrace tunnel of the resistivity rises at 45°, the turning point corresponding to AB/2 is larger than or equal to 38 m, and the turning point of the resistivity curve is less than 30 m,with obvious induced polarization rate anomalies.
