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。
The problem of seepage with free surface is a rather complicated nonlinear problem. The finite element method for solving this kind of problem generally adopts fixed grid method. Based on the seepage characteristics of saturated and unsaturated regions, this paper proposes a Gaussian point method, which is simple in principle and easy to implement.
