Research of Synchronous Jacking up Construction Monitoring and Control Technologies of Bridge

摘要

This study is to optimize the longitudinal linear of the original route based on the jacking up construction of one bridge in the Xiamen-Chengdu Expressway project, which applied the synchronous jacking up construction method to raise the beam and consequently achieve the designed linear. Through the research of the jacking up technology, the synchronous jacking up construction monitoring and control technologies during the whole process of the construction as well as simulate the limit force of the beam by means of finite element software, the accurate analyzing threshold could be offered to the monitoring step.
