Design of Shallow Dish Roadside Ditch in Arid Area——Taking Highway 304 Line from Yanchi to Hongjing in Ningxia Province as an Example

干旱区公路浅碟型边沟设计——以宁夏省道盐池至红井段为例(英文)

In this study, the shallow dish cross-section roadside ditch was designed, based on highway 304 line from Yanchi to Hongjing of Ningxia Province. The hy- draulic calculation of the shallow ditch obtained the corresponding water outlet dis- tance of the ditch with the width of 1.5 m or 2 m suitable for local use under dif- ferent groove longitudinal slope conditions. And the key roadside ditch construction techniques and suitable grass species were introduced.

笔者结合宁夏省道304线盐池至红井段公路,设计浅碟型断面形式边沟,对浅碟型边沟进行水力计算,得出适合本地采用的1.5、2 m宽边沟在不同的沟底纵坡条件下对应的出水口间距,介绍边沟施工技术要点,并推荐适合的草种。
