Integrated Conceptual Design of Underground Space in Suzhou North Railway Station Hub Area

Under the background of the construction of national high-speed railways and the highly intensive development of cities, the integrated development of comprehensive transportation hubs and their underground spaces has been rapidly advancing. Taking the renovation of Suzhou North Railway Station as an example, the conceptual design plan for the integrated underground space in the core area of the Suzhou North Railway Station hub is explored. By considering the current development status, planning conditions, and regional positioning of the Suzhou North Railway Station hub, the problems existing in the current development of the underground space of the hub are identified. Guided by the design goals, principles, and vertical relationships of the underground space of the hub, the main control parameters for the underground space design are determined. Oriented towards the problems and functions, and in combination with the favorable development trend of new transportation modes, the conceptual design plans for the floor plans of each level, main axes, and vertical relationships in the core area of the Suzhou North Railway Station hub are proposed. The construction scale of the underground space in the core area of the Suzhou North Railway Station hub is clarified, providing technical guidance for the expansion and renovation project of Suzhou North Railway Station and offering certain experience references for the development and design of underground spaces in the core areas of other high-speed railway hubs.
