平原区高速公路低路堤设计研究

Research on Design of Low Embankment of Expressway in Plain Area

平原区高速公路路基设计受净空、路基干湿状态、排洪、通航和横向通行等因素影响,一般采用具有一定填土高度的路堤,造成大范围取土占地、生态破坏,有悖于绿色发展理念。本文从节约土地、绿色发展理念出发,就平原区高速公路低路堤设计与其他设计方案进行对比分析,探讨平原区高速公路低路堤设计的可行性。

The design of highway subgrade in plain area is affected by factors such as clearance,subgrade dry and wet state,flood discharge,navigation,and lateral traffic,which generally uses embankments with a certain fill height,causing large-scale land acquisition and ecological damage,which is contrary to the concept of green development.Starting from the concept of land saving and green development,this paper compared and analyzed the design of low embankment of expressway in plain area with other design schemes,and discussed the feasibility of low embankment design of expressway in plain area.
