北赵引黄灌区二期工程输水线路过沟段设计方案比选

Comparison and Selection From Design Schemes of Gully-passing Water Diversion Line of the Beizhao Yellow River Diversion Proiect( Secoud Phase)

根据北赵引黄灌区二期工程引水主干线将要跨过的杨李沟的地形地质情况,提出了三个设计方案,即渡槽方案,架空式侧虹方案和缓坡式倒虹方案。文中叙述了三个方案的结构设计,水力计算和工程概算。最后通过比较,选定了缓坡式倒虹方案。

According to the actual topography and geologic conditions of the Yangli Gully,across which the main water diversion line of the Beizhao Yellow River Diversion Project（ Secoud Phase） will pass,three design schemes are presented.There are aqueduct scheme,aerial inverted siphon scheme and gentle slope inverted siphon scheme. The paper introduces these schemes＇ structure design,hydraulics calculation and project budget estimates. At last,through comparison the gentle slope inverted siphon scheme is selected.
