Concrete-filled Steel Tubular Basket-handling Arch Bridge Vertical Swivel Construction Control Simulation Analysis

Since rib-hoisting of the long-span CFST are hbridge is very complex, method of simulation caleulation of construetion control must be adopted in rrder that the final bridge line and the state of strength will satisfy the requirement of design.This paper makes a historical of review of the development of arch bridges through their early development,their condition of research and their trend ofdevelopment.On the basis of HuTuohe Bridge of Sanmenkou sea-crossing in HeBei Province,this paper study some contents as follows:(1)This paper detailedly expounds the main content,principles,methods and the influencing factors of construction control.(2)Space model of Concrete-filled Steel Tubular arch bridge was set up by finite element analysis software for bridge structure to analyze structure procedure the construction course.Based on the structure's analysis of the construction,the development of stress and displacement during construction was predicted to provide direction for actual construction.In order to ensure that the ultimate bridge line and force a state to meet the design requirements,a real-time monitoring system of HuTouhe Bridge has been set up. Throughout the construction process of the simulation analysis to this CFST arch bridge with tie bars,as well as the calculation results and field monitoring data analysis and comparison,the theoretical value is good agreement with the measured results.This indicates that this paper used finite element analysis method can better reflect the actual construction of the bridge construction. That Concrete-filled Steel Tubular basket-handling arch bridge Vertical swivel construction control simulation analysis can play the better instruction role to the fenghui bridge construction monitoring.
