Chengdu-Dazhou-Wanzhou High-Speed Railway Suining Fujiang River Super-Major Bridge
The Suining Fujiang Special Bridge is a key control project of the Chengdu-Dazhou-Wanzhou High-Speed Railway. In December 2022, the first pile of the main tower was driven. It adopts an "H"-shaped double-tower double-suspension plane steel-concrete composite beam cable-stayed bridge structure. The main span length is 305 meters, ranking first in the southwest region and second in the country.
As of December 2024, the main tower was completed and topped out. In April 2025, the first section of the steel box girder was lifted and installed. A total of 4 sets of viscous dampers were used, with the following models and parameters:
Model | Damping Force（kN） | Displacement（±mm） | Qty (set) |
FVD-2500/±250 | 2500 | 250 | 4 |
