基于抽水试验确定含水层水文地质参数计算方法

Discussion on calculation method of determining hydrogeological parameters of aquifer based on pumping test

以东营农高区农产品电子商务综合楼项目现场抽水试验为基础,为查明场地含水层渗透性,测定含水层的渗透系数、影响半径等水文地质参数,运用潜水非完整井非稳定流抽水数学模型,利用解析法和图解法计算含水层渗透系数和影响半径。所用方法可为东营地区类似工程计算含水层水文地质参数计算提供参考。

Based on the on-site pumping test of the agricultural product e-commerce complex project in Dongying Nonggao District,in order to find out the permeability of the aquifer of the site,determine the permeability coefficient of the aquifer,the influence radius and other hydrogeological parameters,and use the unsteady flow pumping mathematics of the submerged incomplete well the model uses analytical and graphic methods to calculate the aquifer permeability coefficient and influence radius.The method used can provide reference for calculation of hydrogeological parameters of aquifer in similar projects in Dongying area.
