Finite Element Analysis Of Continuous Girder Bridge In Cantilever Construction

Prestressed concrete continuous cirder cridge has benn wildly used in long-span bridge for its excellent performance in structure. But along with its span unceasingly increasing,the construction request is higher, also brings some inconvenience in construction,and even there have been some problems.This paper take the actual situation in continuous beam bridge construction monitoring projects as the background,analyzed Cantilever bridge construction monitoring pouring Ways and the problem construction monitoring should be paid attention to. Set up a bridge structure calculation model with large general-purpose finite element software ANSYS,which carries on the simulation analysis with bridge through out the construction process,analysis of calculated results has high relevance,Provide an effective basis for install template in bridge construction and structure of power status. Through simulated temperature field of bridge structure,Analysed the Temperature effect in the process of cantilever bridge construction,provided reference for control of the bridge linear better. Such analysis provide significance of theoretical guidance for depth study of the similar bridge construction and research.
