摘要
$本文在分析有关文献的基础上!给出了描述地下水在饱和带和非饱和带中运动规律的数学模型,即相应的偏微分方程及其定解条件,并通过对二维渗流方程的求解,简要介绍了Galerkin有限元方法以及非线性偏微分方程的迭代解法。
This article based on the understanding of related literatures will derive the mathematical model which describes the movement of groundwater in saturated zone and unsaturated zone, that is, it will give relevant equations and their determining conditions. A brief introduction to Galerkin finite element method, iteration method solving nonlinear partial differential equation is included in this paper by, introduing a method to solve two—dimensional water folw in saturated —unsaturated zone.
