摘要
本文对地下水运动数值模拟过程中边界条件的涵义和处理方法进行了分析和讨论。阐述了边界条件所包含的双重意义。指出随着人类活动影响强度的日益增大,边界条件的处理要面临一些新的更为复杂的问题。在模型预报之前必须首先对边界条件做出预报。边界条件的预报既要考虑自然因素的作用,同时也要考虑人类活动(人工开采和人工补给)的影响及由于邻区水流条件变化而产生的耦合效应。之后,给出了两个应用实例。
The implication and disposal methods of the boundary condition in the numerical simulation of groundwater flows was discussed in this paper. The double meanings that the boundary condition possesses were elaborated. The boundary condition is being faced with some new and more complicated situations due to the intense growth of mankind activities. The boundary condition must be predicted before the model simulation. In the boundary prediction, the natural factors, mankind activities and the coupling effect induced by the water flow variation in neighbor areas should all be considered. Two actual examples were studied by applying the proposed approach.
