重庆外环高速公路支坪收费站改扩建方案探讨

Discussion on Reconstruction Scheme of Chongqing Outer Expressway Zhiping Toll Station

为了解决高速公路支线收费站改扩建过程中的方案比选形式及方案中应思考并慎重对待的问题,结合已有相关研究成果,以重庆外环高速公路支坪收费站改扩建中存在的问题及方案比选优化为依托,采用缩短服务时间、设置单岛多亭车道及纵、横向增加土建车道等方案进行比较,并分析了各方案存在的优缺点,得出了在以重型货车或大型客车为主的支线收费站,应以横向增加收费车道来达到扩建既有收费广场的结论,以期为类似收费站的改扩建方案比选提供参考。

In order to solve the problem that should be considered and treated seriously in scheme comparison and selection of expressway toll station reconstruction and expansion,this paper based on the relevant research achievements of predecessors and the scheme comparison of Zhiping Toll Station′s reconstruction,discusses the schemes such as shortening the service time,setting the single island multi-tower lane and increasing the civil construction lanes in the vertical and horizontal directions.This paper also compares the advantages and disadvantages of each scheme,and draws a conclusion that the toll station′s reconstruction with trucks or large buses should be made by expanding the toll lanes horizontally to expand the existing toll plazas.This paper can provide reference for similar toll station′s reconstruction and expansion.
