Research on the Monitoring Technology of Cantilever Construction of Continuous Girders in Super Large Bridges

Abstract:

For the construction of large bridges, it is a very critical and difficult issue to obtain the pre-designed internal force state and geometric alignment through the control on the construction process when they are completed. This paper, according to the real-time monitoring results of the bridge structure in the construction process, assesses the deformation of the main components in primary construction phases as well as whether the variations of stress conform to the design requirements, security of construction process, and working state of structures.
