Abstract

To investigate the impact of temporary structures on the mechanical behavior of shaped bridge towers during the construction process, the Dianbu River Special Bridge was selected as the engineering background. A finite element model of the middle tower column during the construction stage was established using ABAQUS to analyze the effects of key parameters, including the angle and pretension of temporary cables, as well as the wall thickness and diameter of temporary diagonal braces. The study examines how these parameters influence the stresses at the tower-girder consolidation. The results indicate that the angle of temporary cables significantly affects the tensile stresses at the tower-girder consolidation, while its impact on compressive stresses is minimal. Among all parameters, the pretension of temporary cables has the most pronounced effect on the stresses at the tower-girder consolidation. In contrast, the wall thickness of temporary diagonal braces has only a minor influence, whereas the diameter of temporary diagonal braces has an almost negligible impact. These findings provide valuable insights for optimizing the design and arrangement of temporary support structures in similar bridge construction projects.
