| Abstrait: |
Based on the design and construction of the second Yangtze river bridge in Wuhu (hereinafter referred to as Wuhu Second Bridge), this article introduces the structure system of the full-floating cable-stayed bridge with four cable planes, single-column tower and separated steel box girders. A series of innovative structural measures have been taken to improve the safety and economy of the bridge, such as the looping stayed cable anchorage system, the diagonal damping constraint system, and the externally prestressed segmental assembled box girder used in the approach bridge. In addition, the finite element analysis software was used to study and analyse the mechanical characteristics of the bridge. The reliability of the structural anchorage system and damping constraint system was verified either. |
