| 摘 要： | 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。

| Abstract: | This article presents a new numerical method to analyze the seepage through the saturated/unsaturated soils of levees or dams. This method is based on the mathematical model established in terms of the seepage regulations of saturated and unsaturated soils and compiled by coupling the saturated zone with unsaturated zone as a whole. The model is computerized by means of finite-difference method. Under the drop down condition of the upstream water level, the calculated results compare fairly well to the test results.The distribution of the seepage lines and isopotential line (isobaric lines) is reason-able and regular. |
