城市道路拓宽改造横断面选型要点分析

Analysis on the Key Points of Cross Section Selection for Urban Road Widening and Reconstruction

以辽宁省大连市高新园区城市主干路红凌路拓宽工程为例,针对道路拥堵严重的问题,采用通行能力分析的方法,并考虑用地限制、避让管线、保留树木等因素,研究城市道路拓宽横断面的选型,并给出了具体示例。道路拓宽根据实际情况分路段选择最适宜的横断面形式,能够在较好地改善道路交通拥堵问题的同时,降低工程难度,提高工程经济性,达到可持续发展的目标。

Taking the widening project of Hongling Road,the main urban road of Dalian High-tech Industrial Park in Liaoning Province,as an example,in view of the serious problem of road congestion,the method of traffic capacity analysis is adopted,and the factors such as land use restriction,avoidance of pipelines,and preservation of trees are taken into consideration to study the selection of urban road widening cross section,and a specific example is given.According to the actual situation,the most appropriate cross section form is selected for road widening by section,which can reduce the difficulty of the project,improve the economy of the project and achieve the goal of sustainable development while better improving the road traffic congestion.
