| 摘 要： | 提出了用于渗流分析的流形单元法。该方法用物理覆盖来确定材料的分区与自由面，通过迭代求出自由面边界，计算区域逐步逼近实际渗流区域，适用于稳定和非稳定渗流计算。算例表明，该方法用于有自由面的渗流分析是简单有效的。

| Abstract: | A new method, named numerical manifold element method, is put forward for seepage with free surface problem. In this method, the partition of material and free surface is determined by means of using physical covers. Through iterative operation, we can calculate the boundary of free surface and make the calculation area draw near to the practical seepage area step by step. The two cases show that the numerical manifold element method is simple and effective in resolving the problem of seepage with free surface. |
