浅谈山区高速公路互通立交总体设计

The Discussion of comprehensive designing for Highway Grade Separation of Mountain Areas

互通立交是高速公路对外联系的主要纽带,其总体布局是否合理、方案是否可行关系到高速公路建成后的社会效益和经济效益。特别是在山区高速公路建设中,由于地形限制,如设置不当将造成工程规模大幅上升,对项目总投资产生重大影响。本文结合粤赣高速公路建设,介绍了山区高速公路互通立交总体设计的思路和方法,可供同行参考。

The grade separation interchange is the main tie for the highway to link the external world. Whether the overall arrangement is reasonable or the program is feasible has much to do with the social effects and economic benefits. Particularly during the construction of mountain areas＇ highway, the project scale may be enlarged resulting of raising the overall investment, if the design is unreasonable with the limit of topography. This paper combined the construction of Yue-Gan Highway, and introduced the comprehensive designing for highway grade separation of mountain areas. For reference to the sane occupations.
