| Abstract: | This paper took some prestressed concrete continuous girder bridge in the process of cantile- ver cast-in place construction as the background. It could ensure the safety of the structural analysis and made the line type of the final bridge meet the design requirement successfully after through the construct ion stage o f continuous girder bridge simulation analysis and each segmental linear and cam- ber field monitoring. Finite element analysis of the main bridge through camber draw relevant conclu-sions on the latter construction has certain marketing and reference value. |
