摘要

根据对淤地坝的结构特征及运用状态的分析，认为确定淤地坝浸润线的合理模型应为透水地基上均质土坝在具有水平上游承压坡的渗流模型和具有垂直承压坡的渗流模型的叠加，其解可按前苏联科学家涅里松—斯柯尔尼亚科夫的２种典型公式叠加计算。实例计算表明，该方法既安全可靠，又经济合理。

Abstract

Based on analyzing the structure feature and operation state of silt arrester

the result shows the rational model to determine the seepage line of silt arrester should be to superpose the seepage flow model with horizontal upstream pressure slope upon the seepage flow model with vertical pressure slope of uniform earth damon the permeable stratum base.The solving process can be superposed by means of two type formulas set by the scientists of the former Soviet Union. The practical calculation indicates that the presented method is reliable and reaso nable.
