Construction Monitoring And Control Technology Research Of Qi Yi Bridge

With the development of Chinese transportation career and modern economics, ing, prestressed concrete continuous rigid-frame bridge obtained rapid development.. The continuous rigid-flame bridge has been applied more and more in construction in the recent years with it’s unique predominance of bridge pier beam consolidation, continuous beam body, handy construction, economical cost, reasonable internal force and comfortable travelling.Because symmetrical construction of the bridge using the cantilever construction method, the deformation and stress of the bridge structure is very complex, in order to ensure the safety and quality of construction in the bridge construction process, making the bridge into a bridge shape and internal force to the maximum extent meet the design requirements, construction controlis is an important part of an integral bridge construction.Based on the106National Highway "Qi-yi Bridge", this paper using finite element analysis software Midas/Civil on bridge simulation and analysis. The bridge is monitored on site, and the theoretical and practical value will be effective combining analysis contrast, btaining the stress and deflection of the bridge in each condition, which has always been in control of the design scope to guarantee the bridge’s safe.The bridge closure across the whole bridge marked the main structure of the basic completion, it is also the most important aspects in the process of bridge construction. This paper based on some reasonable scheme of the bridge colsure and closure temperature, has certain reference function.
