摘要
有自由面的渗流问题是比较复杂的非线性问题，这类问题的有限元求解一般采用固定网格法。本文根据饱和区和非饱和区的渗流特点，提出了高斯点法，该算法原理简单，易于实现。
Finite element method for numerical analysis of seepage with free surface is a complicated nonlinear prob- lem. Some methods , such as fixed mesh method , have suggested to solve the problem. However, each method has its weak- ness. Based on the characteristics of saturation zone and unsaturation zone , a new method called Causs point method has proposed to improve the precision of numerical computation.
