Simulation Analysis on Construction of Liangjiang Great Bridge

Liangjiang Great Bridge is the prestressed concrete continuous rigid frame bridge with high pier and long-span. It adopts the segmented cantilever construction method. The process of its construction is the key to the construction control simulation analysis. In this paper, based on the characteristics of the bridge construction, finite element method is used to establish the simulation model. Cantilever construction stages and closure stages of bridge are simulated and analyzed. The structure deflection diagrams in the each section construction and the later construction considering the creep and shrinkage of concrete are obtained. The initial camber of each segment is given in the construction. The stress characteristics of key section are analyzed in the construction process. It provides a basis for monitoring and on-site construction of bridge and the reference for similar bridge construction.
