摘要
根据邯郸县水文地质条件,建立水文地质概念模型和地下水流数学模型,采用可视化标准软件Visu-al Modflow对研究区地下水进行数值模拟计算及预测。通过自动与手动相结合的方式,多次对模型进行调整,实现模拟计算结果与实际观测值的较好拟合;并以调节均衡型开采动态为原则,制定了2015、2020年县域浅层地下水设计开采量方案。模拟结果表明,2011年至2015年地下水位有明显下降趋势,地下水位下降3 m,2015年以后,在限采条件下,控制开采量,地下水位平均降深稳定在3.5 m左右,流场趋于稳定。
According to hydro-geological conditions of Handan County,the hydrogeology conceptual model and groundwater mathematical model are built.The software Visual Modfolw is used to simulation and prediction in the researching area.Through the combination between automatic and hand to adjust to the model,it can get a good fitting between calculation results and the actual observation values.Based on the principle which adjust exploitation dynamic with equilibrium types,the blue prints of shallow groundwater exploitation capacity are designed for the year 2015 and 2020 and the ground water changed situations are predicted in Handan County.The groundwater level has been down trending obviously between the years from 2011 to 2015,it will down 3 meters.The groundwater will down to stable at the level with 3.5 meters averagely under the limited situation.The results provides a scientific basis for the evaluation and utilization of groundwater.
