The Study Of Construction Control Technique On Railroad Steel Box Arch And Continuous Girder Bridge

The steel box arch and continuous girder bridge has advantages of good mechanical performance, long span ability, simple and elegant shape and so on, It has strong competitiveness in the construction of bridges.In the construction of steel box arch and continuous girder bridge, it has multiple changes in the forces, many construction phase, long cycle of construction, complex influencing factors, construction monitoring can effectively avoid a far deviating from construction, it can guarantee the quality of work and the use of safety. Based on the construction of(32+64+32)m steel box arch and continuous girder bridge, the theory and methods of construction control technology was introduced in detail. The finite element model of the bridge was established by the Midas/Civil software to simulate the major phases in the bridge construction process simulation, at the same time to analyze the stress and deformation of bridge. And make the check calculation for force to the cast stent of bridge. Based on the theoretical analysis results, this bridge carried out on-site monitoring, the continuous steel box arch and continuous girder bridge construction monitoring is ultimately proved to be successful, At the same time it also play a certain guiding role in the similar construction of the bridge in the future.
