Fenhu Station is the intermediate station of Shanghai-Jiangsu-Hubei high-speed railway under construction.It is located in the Fenhu Economic Development Zone of Wujiang District,Suzhou City,and forms a cross station with the planned Tongsu-Jiayong Railway.With the development of the Yangtze River Delta integration as a national strategy and the establishment of an integrated demonstration area,as the only high-speed rail station planned and under construction in the demonstration area,Fenhu Station has gradually risen from the initial general intermediate station to the portal hub station of the Yangtze River Delta integration demonstration area.The local government intends to build it into a model of multi-network integration and station-city integration,and plans to introduce multiple rail transit lines.There are few cases of cross station configuration in high-speed rail design,and the introduction of multiple rail transit lines will increase the design difficulty.Therefore,this study conducted in-depth research on the scheme of introducing rail transit lines into Fenhu Station as a reference.
