公铁合建地下车站与既有高架车站换乘方案研究

Transfer scheme design between new highway-railway joint constructed underground stations and existing elevated stations

依托武汉市轨道交通7号线与既有1号线换乘的三阳路站,从公铁合建方案、站台方案比选、换乘方案等方面对公铁合建地下站与未预留条件既有高架站的换乘方案进行讨论分析。研究表明,通过充分利用公路隧道下部空间布置站厅及设备,并设置轨下通道进行换乘,可大幅缩小车站规模,节省投资。通过设置换乘专用通道代替地面厅,实现城市核心区有效换乘,乘客经由7号线地下二层直达地面,通过三阳路与京汉大道交叉口设置的市政过街天桥实现付费区换乘,同时满足行人非付费区过街需求。方案研究整体合理,可为今后类似工程结构提供设计参考。

This study focuses on the interchange dynamics at Sanyang Road Station,a pivotal junction where Wuhan rail transit line 7 converges with the existing line 1.Specifically,it delves into the transfer scheme between an underground station jointly constructed for highway-railway integration and a pre-existing elevated station that lacks reserved interchange conditions.This analysis encompasses considerations such as the highway-railway joint construction scheme,platform scheme selection,and transfer scheme.This study shows that by optimizing the lower space of the highway tunnel and ramps for the station hall and equipment,as well as setting up a track underpass for transfers,the scale of the station can be greatly reduced and many costs can be saved.Furthermore,introducing a dedicated transfer passage instead of a ground hall facilitates effective transfers in the city's core areas.Passengers could go directly to the ground via the second underground floor of line 7,and then use the municipal overpass at the intersection of Sanyang Road and Jinghan Avenue for paid area transfers,while simultaneously addressing the need for non-paid area pedestrian crossings.This proposed scheme presents a well-structure design and serves as a valuable reference for future projects with similar engineering structures.
