| 摘 要： | 本文介绍了一种求解地下水流问题的有限分析法,该方法将解析解结合到数值方法中,从而提高了计算精度,改善了稳定性。算例表明,在网格尺寸相同的情况下,有限分析解比有限差分解高一个数量级,与解析解吻合很好。

| Abstract: | This paper introduces a finite analytic method of solving groundwater flow. This method combines analytic solution with numerical method, and can rise computational accuracy and improve the stability. The numerical experiment shows that the results of finite analytic method are one order of magnitude higher that those of finite difference method when the size of mesh are the same. This is consistan very well with analytic solutions. |
