在水文地质计算中,正确认识和处理边界条件是至关重要的。文献《一维优化搜索联合有限元方法计算渗流二类边界》(以下简称《边界》)利用一维搜索结合有限单元方法计算流量和水位随时间和随空间变化的边界条件(以下简称变边值问题)。笔者认为该文所述方进在反映变边值问题的特点方面有值得商榷的地方。本文分析了《边界》方法的不足。并提出了适合于该文所述变边值问题的计算方法。
In hydrogeological calculation, it is of crucial importance to understand and handle the boundary conditions correctly. The literature “one-dimensional optimal search combined with finite element method to calculate seepage flow two boundary” (hereinafter referred to as “boundary”) using one-dimensional search combined with finite element method to calculate the boundary conditions of flow and water level changes with time and space (hereinafter referred to as variable edge problem). The author thinks that Fang Jin mentioned in this article is worth discussing in reflecting the characteristics of the variable boundary value problem. This article analyzes the shortcomings of the “border” approach. And proposes a calculation method suitable for the variable boundary value problem described in this paper.
