地下水流数值模拟在白界水源地开采方案设计中的应用

Application of Groundwater Numerical Simulation for the Determination of Optimal Exploitation Scheme in Baijie Water Source

在详细分析白界水源地水文地质条件的基础上,建立了计算区的水文地质概念模型及数值模型,并应用Visual MODFLOW软件对模型进行了求解。通过模型识别及验证表明模型可以用来描述地下水流特征。根据预设的开采方案,通过对预测结果的分析选出了方案4为最优开采方案,其包含49口抽水井,在预定分布模式下,抽水量为163.27 m3/d。

Detailed study on hydrogeological conditions of Baijie water source were carried out in the paper, based on which conceptual and numerical models were obtained. The numerical model is calculated using Visual MODFLOW software. The calibration and verification results show that the numerical model is appropriate to describe the groundwater flow. Several exploitation schemes were designed, and an optimal exploitation scheme was obtained by analyzing the prediction results. The results show that the scheme 4 is the optimal scheme with 49 pumping wells, and the pumping pattern is distribution with a pumping rate of 163.27 m3/d.
