Jinnan Bridge
Jinnan Bridge is a river-crossing passage connecting Tongchuan District and Dachuan District in Dazhou City, Sichuan Province, China. Located over the Zhouhe River Waterway, it is the first two-pylon double-cable-plane cable-stayed extra large bridge in Dazhou City, and also a key control project of the Middle Horizontal Road in Dazhou's ‘Three Horizontals and Five Verticals’ transportation framework. The main bridge adopts a span arrangement of (150+300+150) meters with a total length of 606 meters (including abutments), and is a two-pylon double-cable-plane prestressed concrete cable-stayed bridge.
The bridge was completed and opened to traffic in December 2017, with 4 sets of viscous dampers applied. The model and parameters are as follows:
Model | Damping Force（kN） | Displacement（±mm） | Qty（set） |
OTP 200/600 | 2000 | 300 | 4 |
