| 摘 要： | 利用电测深成果(含水层电阻率或地层因素)估算含水层渗透系数的问题,前人已做了很多工作1,2].作者针对安阳市安阳河北水源地电测深资料的解释和水文地质勘察成果,提出采用电测深K型曲线极大值计算水文地质参数的方法,建立了ρs max～K之间的4种回归分析模型.结果表明,K与ρs max存在对数相关关系.经计算的成果图件(K、T等值线图)对评价该区水文地质条件,估算单井涌水量及水井位置选择等都具有十分重要的实用价值.

| Abstract: | Much work has been done by previous workers concerning the estimationof permeability coefficients of aquifer by utilizing electrical sounding results(resistivity of aquifer or factors of strata). In accordance with interpretationof electrical sounding data and results of hydrogeological survey for the wa-ter source north of the Anyang River in Anyang City, the author has putforward a method for calculating hydrogeological parameters by utilizing ma-ximum value of electrical sounding K type curve, and estabished four sortsof regression mode1 for ρsmax versus k. Studies show that there exists a lo-garithmic correlation between k and ρsmax. The maps of outcomes compiledthrough calculation(k, T contour maps)prove to be of very important practi-cal value in evaluating hydrogeological conditions of this area, estimating wa-ter-gushing quantity of single well and selecting localities for wells. |
