【 摘 要 】

The first phase of Chongqing Rail Transit Line 9 is the first urban rail transit PPP project in China. The General Contracting Headquarters conducts integrated design and construction research at Baoshenghu station on the 9th line. On the basis of the preliminary design documents, the deep drawing design of the super-large section underground excavation subway station was carried out and the application was supervised on the site, and good benefits were obtained in construction safety, quality and progress. The integration of design and construction of the subway station with large section of the No. 9 line was first implemented in the rail transit industry, laying the foundation for the further promotion and application of the design and construction integration under the PPP mode.
