摘要
为满足河北省唐山市丰南城区用水需求,解决高峰期供水不足问题,拟在北刘堼水源地原有18眼水源井基础上,增建6眼水源井。为此,本文采用Visual MODFLOW数值模拟方法建立水文地质概念模型和数学模型,按照拟建开采方案分别对项目满负荷开采2、5、10、20年后的地下水流场及降深场进行预测,从而得到新增水源井地下水位降深值、地下水位平均降速、漏斗中心降深变化情况。
In order to meet the water demand in Fengnan City and solve the problem of insufficient water supply during peak periods,it is planned to build 6 additional water source wells on the basis of the original 18 water source wells in the water source area of Beiliuheng.Therefore,the Visual MODFLOW numerical simulation method is used to establish the hydrogeological conceptual model and mathematical model.According to the proposed mining plan,the groundwater flow field and drawdown field after the project is fully mined for 2,5,10,20 years and get the change of the groundwater level drop value,the average groundwater level drop speed,the depressioncenter drop for the newly added water source wells.
