中心城区轨道交通与快速路复合廊道建设方案探讨

Discussion on the Construction Scheme of the Composite Corridor of Rail Transits and Expressways in Central Urban Area

为适应中心城区内轨道交通和城市快速路不断建设需求,解决中心城区内线位廊道稀缺、实施条件苛刻等问题,提出建设复合交通廊道的理念。通过对现行技术标准、规范中关于轨道交通与城市快速路线形指标的分析,提出适合在中心城区内轨道交通与城市快速路8种可能的共线模式。最后结合长沙市万家丽路轨道交通与快速路共用廊道的实际案例,为以后类似工程建设提供参考。

In order to meet the needs of the continuous construction of rail transit and urban expressways in the central urban area,and to solve the problems such as the scarcity of line corridors and harsh implementation conditions in the central urban area,the concept of building composite traffic corridors is put forward.Based on the analysis of the shape index of rail transit and urban expressway in the current technical standards and norms,this paper puts forward eight possible co-line modes which are suitable for rail transit and urban expressway in the central urban area.Finally,combined with the actual case of the shared corridor of Wanjiali Road Rail Transit and Expressway in Changsha City,this paper provides a reference for the construction of similar projects in the future.
