Analysis of Damage to Suspension Rods and Research on Construction Monitoring Methods for Replacement of Middle Through Arch Bridges
In order to explore the mechanism of damage to suspension rods in arch bridges and the monitoring methods for suspension rod replacement construction,starting from the composition structure of suspension rods,this paper analyzes in detail the damage and generation mechanism,introduces several common suspension rod replacement methods and processes,and develops a complete set of suspension rod replacement construction monitoring methods bydual monitoring indicators of internal force and linearity.Finally,taking a suspension rod replacement project of a mid through tied arch bridge as an example,this paper verified the feasibility of this method.The research results can provide reference and guidance for the maintenance and reinforcement of arch bridges of the same type as well as the replacement of suspension rods.
