摘要

提出了用“空气单元”模拟排水孔的思路，即将排水孔看作是以空气作为渗流介质的单元体，在给定了相应的渗透系数后，使它像岩块、土体等单元一样加入传统的有限元渗流计算方法中。通过算例及实际工程应用，证明该法简便可行，具有一定的工程应用价值。

Abstract

Air element method is proposed to model drainage holes in seepage analysis. The method is to look drainage holes as some elements filled with air. By defining certain higher permeability coefficient

these elements can be included in the conventional seepage calculation like common elements. It is proved by the engineering example that the method is easy to be applied in the engineering practices.
