罗城经怀宝至融水洞头公路越岭段路线方案研究

Study on the Route Planningfor Ridge-crossing Section of Luocheng-Huaibao-Rongshui Dongtou Highway

山区越岭段路线方案设计是整个项目路线设计的关键。文章结合罗城经怀保至融水洞头(罗城至风吹坳段)公路项目,从工程地质、技术经济、工程规模、方案实施、环境保护等方面,对该项目的灯美山至终点(风吹坳)段经平洞岭和经白岩坳的越岭段路线方案进行综合比选与论证,为类似山区越岭段路线方案设计工作提供参考。

The design for the route plan of ridge-crossing section in mountainous area is the key to the whole project route design.Combining the project of Luocheng-Huaibao-Rongshui Dongtou（Luocheng-Fengchuao section）Highway, and,from the aspects of engineering geology, technical economy, project scale, program implementation, and environmental protection, this article conducted the comparative selection and demonstration for the ridge-crossing section route plan of this project＇s Dengmeishan-Terminal （iFengchuiao）section via Pingdongling and via Baiyan＇ao,thus providing the reference for the route plan design work of similar ridgecrossing sections in mountainous area.
