The first carbon fibre cable-stayed vehicular bridge 

in China was hung in Liaocheng

On December 10, Liaocheng Xinghua Road Bridge across the Tuixi River held a hanging ceremony, which is the first domestic application of carbon fiber material cable-stayed bridge of 1,000 tons of traffic. At present, with the installation of the cable-stayed bridge across the Tuixi River Bridge on Xinghua Road, marking the main construction of the bridge has been fully completed; at present, the bridge deck and the asphalt surface layer of the Shunjiang Road are all paved and completed, the bridge has been opened to traffic conditions. After the completion of the bridge, it will effectively relieve the traffic pressure of the east-west direction of the Tuixi River in Liaocheng City and form a strong support for the economic and social development of Liaocheng City.

It is reported that the contract completion time of Xinghua Road bridge across the Tu Shi River is June 18, 2022. The construction unit in charge said it will focus on the strengths of the bridge, and gradually improve the construction of ancillary facilities, steel tower decoration, bridge lighting, road greening and traffic facilities, etc., is expected to achieve the official opening in May next year.

It is understood that carbon fiber is a filamentary material, excellent performance, density is only 1/5 to 1/4 of the steel, but the strength is 7.6 to 15 times the ordinary steel, lightweight and high strength performance is very outstanding. Carbon fibre is used for the first time in China for cable-stayed bridges, and the 100m span is the largest span of carbon fibre cable-stayed bridges in the world. According to experts, academicians of the Chinese Academy of Engineering, Professor Yue Qingrui of the University of Science and Technology Beijing, carbon fiber as a high-performance structural materials, mainly used in the past in aerospace, is a national strategic high-performance fiber composite materials. In recent years, China has made great progress in the application to civil engineering and building structures. The carbon fibre cable used in the Xinghua Road Bridge over the Tuixi River is composed of carbon fibre, resin matrix and fibre/resin interface, and is characterised by its light weight, high strength, reduced structural weight, excellent durability and fatigue resistance, and low operation and maintenance costs during cable service.
