Construction Monitoring and Analysis of Variable Cross-section Corrugated Steel Web PC Composite Box Girder Bridge
As a new type of bridge structure,the variable cross-section corrugated steel web PC composite structure bridge has gradually been favored in engineering.Taking the corrugated steel web composite structure bridge over Xuhong river as the research case,the bridge type layout characteristics and construction sequence of the bridge are firstly introduced.Secondly,the beam and girder framing model for the construction process of the whole bridge is established by utilizing the Midas Civil finite element analysis software,and the setting of precamber and the elevation requirements of the formwork erection during the design and construction are elaborated in detail.Finally,the apparent condition of the main bridge,the elevation of concrete formwork erection,the deflection of the main beam,the settlement of the main pier and the layout scheme of the concrete strain measurement point during the whole construction are analyzed.The results show that,during the whole construction of bridge,the difference between the real-time monitoring index values and the design results is small,and the construction scheme is safe and reliable.
