摘　　要：为缓解渝湘高速公路日益增长的交通压力,加快沿线区县旅游资源一体化开发,解决武隆隧道群通行能力不足、运营安全风险高的问题,在交通运输需求分析的基础上,结合地形地质,提出了多个路线方案,并针对设计速度进行了综合分析,确定了120 km/h、100 km/h、80 km/h设计速度的分段建设标准及北中南3个走廊。In order to alleviate the increasing traffic pressure of Chongqing-Hunan Expressway,speed up the integrated development of tourism resources in the districts and counties along the expressway,and solve the problems of insufficient capacity and high operation safety risk of Wulong tunnel group.Based on the analysis of traffic demand and combined with topography and geology,several route schemes are put forward,and the design speed is comprehensively analyzed,and the sectional construction standards of 120 km/h,100 km/h and 80 km/h design speed and three corridors of north,middle and south are determined.
