[Abstract]:Railway steel box arch continuous beam bridge has many advantages, such as good structural mechanical performance, large span ability, simple and beautiful shape and so on, so it has strong competitiveness in bridge construction. During the construction of railway steel box arch continuous beam bridge, there are many changes in force, many construction stages, long construction cycle and complex influencing factors. Construction monitoring can effectively avoid deviation from the design after completion of the bridge, so as to ensure its engineering quality and safety. Based on the engineering background of (326432) m railway steel box arch continuous beam bridge, the theory and method of construction control technology are introduced in detail in this paper. The finite element model is established by using Midas/Civil software to simulate the main construction stages of the bridge, the stress and vertical deformation of the bridge structure are analyzed, and the cast-in-place support is checked and calculated. On the basis of theoretical analysis, the field monitoring of the bridge is carried out and the theoretical and measured comparison is carried out. The results show that the construction monitoring of railway steel box arch continuous beam bridge is successful and has certain reference significance for the construction of similar bridges in the future.
