本文介绍了堤坝渗流分析的一种新方法——饱和-非饱和渗流的数值分析。本方法是根据饱和-非饱和渗流规律建立的数学模型,将堤坝内饱和区与非饱和区耦合在一起,构成整体的分析模型。应用有限差分法编出程序,上机计算。计算与试验对比表明,无论是上游水位骤升还是突降,两者基本上一致。自由水面线、等水头线以及等压线的分布情况都是合理的,具有良好的规律性。
This paper presents a new method for seepage analysis of dykes - numerical analysis of saturated-unsaturated seepage. The method is based on the mathematical model established by the saturated-unsaturated seepage law to couple the saturated zone and the unsaturated zone in the dam together to form the overall analysis model. Application of finite difference method to program, on the computer. The comparison between calculation and experiment shows that the two are basically the same whether it is a sudden rise or fall of the upstream water level. The distribution of free water lines, equal headlines and isobars are all reasonable and have good regularity.
