Study on the Reinforcement and Reconstruction of through Pre-Stressed Truss Arch Bridge
This paper takes Huzhou Baimitang Bridge as an engineering example, expounds the common diseases of through pre-stressed truss arch bridge and their causes. It uses structure calculation software to optimize the reinforcement methods of components, such as arch rib, diagonal brace, tie beam, etc. The results show that pasting steel for arch rib, diagonal brace and pasting carbon fiber sheet for tie beam can effectively enhance the stiffness and the carrying capacity of Baimitang Bridge. The reinforcing methods are good for reference of other similar engineering projects.
