A bridge equipped with high-performance bearings
- Hong Kong-Zhuhai-Macao Bridge: It uses the world’s largest high-damping rubber isolation bearing with a length of 1.77 meters and a width of 1.77 meters.
- Tian’e Longtan Super Bridge: It has adopted 50 sets of intelligent adjustable isolation rubber bearings.
- Bogotá Metro Line 1: It has applied the optimized rubber bearings, which have the advantages such as firm structural connection.
- Huangmaohai Bridge: It has adopted the ultra-high-performance polytetrafluoroethylene sliding plate bearing.
- Chongqing Chaotianmen Bridge: It has installed the spherical bridge bearing with the world’s largest vertical load-bearing capacity of 145,000 KN.
- Qiangkuang Reservoir Super Bridge: It uses the intelligent seismic isolation and damping system of “WSQZ bearing + ring steel damper”.
- Hutong Yangtze River Bridge: It is the world’s first rail-cum-road cable-stayed bridge with a span exceeding one kilometer, which has adopted a number of high-performance materials and technologies.
- Pingtan Strait Rail-cum-Road Bridge: It is China’s first cross-sea railway bridge, and a number of innovative technologies such as the new system for rail-cum-road bridges in complex sea areas have been independently developed for it.
- Wufengshan Yangtze River Bridge: It is China’s first rail-cum-road suspension bridge, and also the rail-cum-road suspension bridge in the world with the highest operating speed, the largest operating load and the largest span.
- Baihe Yujiang Super Bridge: The main bridge of it is the world’s largest double-track ballastless track steel-concrete composite girder cable-stayed bridge with a speed of 350 km/h, which adopts the structural system of “semi-floating + unilateral main tower bearing with horizontal restraint”.
- Shiziyang Passage: High-durability rubber bearings, high-performance graded shock-absorbing steel bearings and replaceable durable friction dampers have been developed and will be applied.
