甘肃靖远黄河谷地第四系含水层电性特征及其水文地质意义

Electrical characteristc of Quaternary aquifers in the Yellow river vaIIoy of China

本文以甘肃靖远地区黄河谷地环境工程地质勘查电测深资料为依据,初步分析讨论了电测深曲线类型分布及变化规律,着重指出了在相同岩性的含水地层中影响曲线形态和类型变化的两个主要因素含水层厚度与矿化度。简要阐明了含水层电性特征在水文地质上的作用和意义。

Based on the electric sounding data from the environmental engineering-geological cxploration in the Yellow River valley of Jingyuan area, Gansu Province, the distribution and variation patterns of electric sounding curves are preliminarily discussed, and two main factors influencing the variation of configuration and types of curves in aquifers of similar lithology are pointed out, i. e. thickness of aquifer and degree of mineralizations. The significance of electrical characteristics of aquifers in the hydrogcological study is briefly elucidated.
