地铁站点施工期间交通组织方案研究

近年来各大城市纷纷修建地铁,而在修建期间的交通问题愈加突出。为了处理地铁施工与城市交通的矛盾、优化地铁施工期间道路交通的组织工作,同时确保地铁施工的有序进行,本文以南昌市地铁2号线为例,研究城市地铁施工期交通组织方案。根据实际情况,分析国体中心站点周边区域道路存在的主要交通问题,综合考虑地铁施工对周边环境的影响,对施工交通组织方案设计进行研究,采用四阶段法对施工期间交通流量重新分配,分析部分道路施工围挡后的通行能力的变化,对地铁站所在路段区域进行交通合理引导和疏解。

In recent yeats, major cities have built subway, and the traffic problems during the construction of subway are becoming more and more serious. In order to deal with the contradiction between subway construction and urban traffic, optimize the organizational work of the road traffic during the subway construction and ensure the orderly construction of the subway, this paper takes the subway line 2 of Nanchang city as an example to study the traffic organization plan of the urban subway during the construction period. According to the actual situation, the main traffic problems in the surrounding area of the central site of the National Center are analyzed, and the influence of the subway construction on the surrounding environment is taken into consideration. The design of the construction traffic organization scheme is studied. The four stage method is used to redistribute the traffic flow during the construction period, and the traffic capacity of the part of the road construction is analyzed. The change of force can reasonably guide and ease traffic in the area of the subway station.
