The project upper part is a complete circle saddle- shaped canopy, with oval shape plane projection. Its long axis is 283.3m, short axis 265.3m, the maximum cantilever of the canopy is about 55m; The east- west front end height is about 51.5m, and the south- north front end height is about 49.7m. The spoke-type cable truss structure is adopted, with each cable truss spacing of about 12m and the height of the front truss pole of 14m. Take above radial cable as the boundary, the project is divided into 36 independent membrane units, of which the maximum membrane unit area is 1256 square meters, the minimum membrane unit area is 750 square meters.
