摘要
一般的U形渠道断面参数包括渠道向外倾斜的直段与铅垂线的夹角、渠道下部圆弧半径、水深、渠道衬砌高度、渠深、渠口宽。U形渠道设计时,常借用U形渠道断面参数表选取参数。介绍了我国规范规定的和相关文献建议的U形渠道断面参数范围,并研究推荐了一种新的U形渠道断面参数表及其函数关系式,实例分析表明,推荐的参数表简单直观,意义明确,安全合理,便于记忆,使用方便,适用范围较广。
Generally U-shaped channels section parameters include the angle between the channels outwardly inclined straight section and the verti- cal, the radius of the arc of the channels lower part, the height of the water depth, the height of channels lining, channels depth and channels mouth width. The design of the U-shaped channels often uses the U-shaped channel section parameter table to select the parameters. The paper de- scribed a U-shaped channel section parameter range recommended by national specification and suggested by relevant literature. It also studied and recommends a new U-shaped channel section parameters and its function relationship. The examples show that it is simple, intuitive, clear, safe and reasonable, easy to remember, easy to use and wider scope of application.
