摘要
文章运用地下水流动系统理论,探讨了时空变化复杂地区水质运移的定量模拟方法。提出时间演变复杂的地下水流动可以用分段模拟法来把握区域渗流轮廓;对复杂的介质场进行逐级等效复原的方法来处理。这种模拟方式既克服了资料不足和剖分数有限的困难,也能提高计算精度。文章以衡水地区咸水运移为例对该方法作了详细说明。
Based on the groundwater flow system theory , authors discuss a quantitative simulated method for groundwater quality problem in a complex region .As the change of groundwater flow with time and space is mostly complex , the time-staged simulated method can be used to the outline of regional vadose field ,and the method called step-by-step equivalent recovery is used to treating medium . The simulated method not only has overcome those difficulties , such as insufficiency of some imformation and finiteness of discrete number , but also improved the calculation accuracy .The paper explains in detail the method with the example of saline water migration in the Hengshui region of Hebei .
