Abstract

When the service life of the suspension rods of arch bridges approaches their designed service life, suspension rod replacement is often carried out. However, at present, cases of replacing the suspension rods of the arch bridge under traffic conditions in China are still relatively rare. Considering the actual operational requirements for heavy load and traffic demand protection of arch bridges, this paper discussed the optimization of the main processes during the replacement of suspension rods, proposed correction methods for key parameters such as monitoring the influence of environmental temperature and vehicle loads during the construction process, as well as an accurate measurement method for the internal forces of short suspension rods, and evaluated the construction effect of suspension rod replacement of arch bridges under the heavy load and traffic demand protection requirements. The results show that all the control indicators of the suspension rod replacement of the arch bridge under the heavy load and traffic demand protection conditions meet the design and specification requirements. The proposed technical method can provide a reference for the replacement of suspension rods in the same type of bridge.
