沪渝高速八岭互通立交方案设计研究

Research on the Design of Baling Interchange Scheme of Shanghai-Chongqing Expressway

针对沪渝高速八岭互通立交设计方案,为了满足未来交通需求,本文首先阐述了互通立交方案设计原则、转向交通量及断面型式,选取线形、经济、节能、环保等评价指标,建立了互通立交路线方案评价体系,采用综合评分法,对提出的两种互通方案分别进行了评价。研究结果表明,方案一在线形、经济性等方面具有明显优势,尤其在与周边旅游区的连接上有明显优势。综合考虑各方面因素,采用方案一作为最优设计方案,以确保沪渝高速八岭互通立交的高效运行。

In order to meet the future traffic demand,this paper firstly expounds the design principle of interchange scheme,steering traffic volume and section type,selects the evaluation indexes of alignment,economy,energy saving and environmental protection,and establishes the evaluation system of interchange route scheme.The comprehensive scoring method is used to evaluate the two interchange schemes.The results show that the first scheme has obvious advantages in linear and economic aspects,especially in the connection with the surrounding tourist areas.Considering various factors,the first scheme is adopted as the optimal design scheme to ensure the efficient operation of Baling Interchange of Shanghai-Chongqing Expressway.
