| Abstract: | The self anchored Suspension bridge with single tower and spatial cable plane, whose main cable shape is a spatial structure, has a parabolic projection on the elevation and plane. During the construction process, the main cable is required to transition from a free plane to a spatial cable plane. Combining with the Fumin Bridge in Tianjin, this article introduces some new design and construction technologies related to spatial cable structures, and briefly describes the specific implementation methods and tensioning methods of spatial cable system transformation |
