Abstract
In response to the construction challenges brought by complex terrain and operating highways,the non guided beam sliding method is adopted,combined with the stress free state method for theoretical analysis and control.Through finite element analysis models,the structural behavior and static equilibrium equations during the closure stage were studied,with a focus on the structural changes under large displacement and small strain.Practice has shown that accurately adjusting the position of the steel box girder on the main and side piers can effectively control the deviation of the closure,ensuring structural docking and mechanical performance.关键词
