Abstract
This paper focuses on the theme of bridge construction control, using the finite element analysis and calculation program as the platform, taking a concrete-filled steel tube concrete basket arch bridge as the research object, combining the theoretical foundation of the concrete filled steel tube basket arch bridge, and using finite element software to simulate the rotating structure in three dimensions Simulation, analysis of the force status and longitudinal and lateral changes of the rotating structure at various angles and when closing, and the structural stability analysis of the rotating process. The most unfavorable stress conditions and the most vulnerable to instability conditions are determined. And through simulation, the accuracy of the line shape of the steel pipe arch rib in the vertical rotation process, the accuracy of the arch axis detection and the accuracy of the elevation detection are estimated.
