Abstract

According to engineering practice, the stress characteristics of long-span box girder are analyzed, especially the technical flaws in design and construction cause beam cracks. The theoretical basis and improvement measures are proposed, and the theoretical depth of optimization design is improved through the summary of breaks. And improve structural quality issues.
