| 摘 要： | 有自由面渗流分析的有限元法一般采用移动网格法，近年来出现了几种固定网格法在扩大了的域上求解，本文在上述方法的基础上，提出了有自由面渗流分析的虚单元法，该法优于上述方法。

| Abstract: | The method proposed is based on finite element method by setting elements over the free surface calculated from the first approximation,as imaginary elements to promote the convergence rate of the numerical computation.Examples used to demonstrate the computational procedure are also presented. |
