基于工程地质地貌的路基排水设计探究

Research on Subgrade Drainage Design Based on Engineering Geology and Landform

本文以长乐市滨江路(岐洋段)道路工程Ⅲ、Ⅳ标段为例,以道路路基排水设计原则为切入点,介绍了路基排水系统组成,分析了边沟、截水沟、排水沟、急流槽与消力池等基本排水设施的设计要点,提出应结合工程地质地貌、结构形式等因地制宜采取合理的工程措施,灵活运用排水设计方案,尽可能以最低的投资获得排水能力强的道路排水系统。

In this paper,taking bid sectionsⅢandⅣof the road engineering of Binjiang Road(Qiyang Section)in Changle City as an example,taking the road subgrade drainage design principles as the starting point,the composition of the subgrade drainage system is introduced,and the side ditch,intercepting ditch and drainage are analyzed.The design points of basic drainage facilities such as ditch,rapid flow trough,and stilling basin,propose that reasonable engineering measures should be taken in accordance with local conditions such as engineering geology,geomorphology,structural form,and flexible use of drainage design schemes,so as to obtain a strong drainage capacity with the lowest investment possible.Road drainage system.
