有自由面渗流分析的子单元法

为克服现有固定网格法解决有自由面渗流问题存在的不足，本文提出子单元法的固定网格法，编制了三维有限元电算程序．经过实例应用。

In this paper an effective solution of fixed meshes named sub element method is proposed in order to raise the efficiency of the existing methods in analyzing the seepage problems. The results obtained from the analysis of some examples are presented to demonstrate the usefulness of the 3 D computational procedure compiled with this method.
