Abstract:Tonghu Avenue Station of Nantong Metro Line 1 is located in the central innovation area. In order to rationally develop and utilize the underground space, the integrated development of subway station and plot is carried out. Because the secondary developers of the plot have not been determined, the ground development mode and scale have not been stable, and the station and plot development are implemented by stages. In the near future, combined with the concept of integrated design, the station should be designed as inclusive as possible so as to reserve the good implementation and construction conditions for the long-term secondary development. By analyzing the preliminary study of the plot scheme, the thinking in the design process of Tonghu Avenue Station, and the deficiencies in the completion process, a useful reference for the other integrated development subway projects implemented by stages is provided.
