电法和数值模拟法在宿州市地下水资源评价中的应用

在对宿州市水文地质条件分析的基础上,介绍了电法进行含水层勘探的基本原理,应用电法勘探对自来水厂拟打开采井位含水层分层进行了勘查,电法勘查数据解释结果与钻探揭示的含水层分层结果有非常好的一致性。结合水文地质钻孔资料和电法勘探资料,构建了第四系含水层结构模型,在此基础上,建立了宿州市地下水数值模型,利用数值模型对宿州市地下水资源量进行了评价,总补给量为18614．04万m^3／a,天然排泄量为4163．8万m^3／a,地下水可开采资源量为14582．73万m^3／a。

The Application of Electrometric Method and Numerical Simulation to Evaluate Groundwater Resources in the Suzhou City,Anhui Province

In this paper, based on the analysis of hydrogeological condition in Suzhou City, the basic princip to investigate th le of electrometric method is introduced. The electrometric method is used e aquifer distribution. The electrometric data and the drilling data have no difference. Combining with those data, the structure model of quaternary aquifer is estab lished. The numerical simulation model of groundwater flow in Suzhou is established by u sing MODFLOW. The model is used to calculate the groundwater resources. The results show that the total recharge resources of groundwater is 18614.04× 10^4m^3/a, the discharge resources is 4163.80× 10^4m^3/a, and the recoverable resources is 14582.73× 10^4m^3/a.
