Research on Construction Point and Safety Verification of Municipal Road Steel Box Girder
In order to ensure the construction quality of municipal road and bridge,this paper summarizes the characteristics of steel box girder.Taking the steel box girder bridge on an urban expressway as the research object,based on the walking incremental launching method,the construction points are analyzed from the aspects of steel box girder prefabrication,hoisting,transportation,guide beam selection,segment incremental launching and beam falling.At the same time,the construction safety of temporary piers and beams is verified.The research results can provide theoretical guidance for similar projects.
