摘要
本文对一般的非饱和渗流有限元计算方法加以改进, 有效地消除了非饱和渗流数值计算中存在的数值弥散现象. 同时还提出了一种简便有效的逸出面处理新方法,
This paper presents an adapted finite element method for unsaturated analysis. Numerical confusion phenomenon in unsaturated seepage numerical analysis is avoided effectively. A new method for seepage spill boundary handling is also presented. Some analysis examples are given.
