高速公路改扩建工程纵断抬高段的交通组织设计及工程实践
Traffic Organization Design and Engineering Practice for Vertical Alignment Elevation Sections in Expressway Reconstruction and Expansion Projects
摘要
Abstract
With the acceleration of urbanization,the capacity of the highway constructed in the early days has been difficult to meet the development demand,and it is urgent to improve their capacity through the reconstruction and expansion projects.Taking the reconstruction and expansion project of the east line of Jinan Round City Expressway from Xiaoxujia Junction to Yaoqiang Airport as an example,the paper analyzes and studies the traffic organization scheme for the characteristics of this project,which is characterized by a large proportion of longitudinal elevated section and a large difference in height between the old and new road base,and focuses on the split construction scheme for the elevated section,and the adopted traffic preservation scheme can effectively balance the construction efficiency with the traffic demand.The research results can provide theoretical basis and practical reference for similar projects,aiming to promote the further optimization of traffic organization scheme for highways in urban areas.关键词
