贵阳东环线工可阶段线位布设与比选分析

The layout and comparison analysis of construction stage line of Guiyang East Ring Road

在工程可行性研究阶段,面临的选择性方案较多,需要考虑区域的发展、资源的开发利用、人们出行便利性等问题。以贵阳东环线前期的工程可行性研究阶段为实例,对公路不同条件下的影响因素进行对比分析,最后得出最适宜建设的路线走廊带,为其他项目的线位布置与复杂情况下的方案比选提供参考,具有一定的现实意义。

In the stage of engineering feasibility study,there are many alternatives,and regional development,resource development and utilization,and people’s travel convenience should be considered.Taking the preliminary engineering feasibility study stage of Guiyang East Ring Road as an example,this paper makes a comparative analysis of the influencing factors under different conditions of the highway,and finally obtains the most suitable route corridor,which provides a reference for the line layout of other projects and the scheme comparison and selection under complex circumstances,which has certain practical significance.
