摘　　要：对于有自由面的求取的渗流问题,介绍了一种可以不进行迭代求解渗流问题的自由面的新方法,并且采用常用的商用软件解决饱和非饱和渗流问题.将新的边界处理方法应用到多种材料的土石坝及坝基的渗流分析中,可以用一般的商用有限元软件进行饱和非饱和、稳定非稳定的渗流问题的计算,并结合某堤防工程进行稳定渗流分析,得到了较好的结果.The ordinary use of finite element method in the analysis of seepage including solving the free surface needs iterations. A new method which can solve 2D and 3D seepage problems without iterations, is put forward. Seepage problems can be solved using any ordinary commercial software. A new method for treating boundary condition is also described. This method can be applied to multi-material seepage analysis. With these new methods, any ordinary commercial finite element analysis software can be applied to solve steady-unsteady saturated-unsaturated seepage problems. An example is analyzed by (using) new methods; and satisfactory results are obtained.
