摘要：Orthotropic bridge deck is the main structural form of steel box girder bridge deck. Due to the dense U-rib weld and complex structure, it is easy to produce large deformation during welding. At present, the determination of the amount of deformation is mainly based on the empirical value and the trial and error method. It is of great significance for welding deformation control to study the influence of welding process on welding deformation of orthotropic bridge deck and clarify the influence of welding parameters and welding sequence. Based on Marc software, the finite element thermoelastic analysis method is used to simulate the post-weld residual deformation of orthotropic bridge deck. The influence of welding parameters and welding sequence on welding deformation is analyzed, and the sensitive parameters affecting welding deformation are determined. The optimal combination of welding parameters was developed, and the reasonable sequence of U-rib welding was established, which laid a foundation for welding deformation control of orthotropic bridge deck.
