Abstract:In recent years, with the increasing traffic volume and traffic load, the force of the original boom cannot meet the requirements of the original design, and more and more maintenance of the boom of arch bridge, such as replacing the boom, will not only bring damage to the bridge itself, but also cause traffic congestion. Based on the practical application of Chengdu Ring-cheng high-speed Fuhe Bridge, this paper introduces the reinforcement system of the bridge and the existing problems in the design and construction, and puts forward suggestions on the existing problems to provide reference for the reinforcement design and construction of similar Bridges in the future.
