Abstract:

Based on the new Foshan Bridge of Guangzhan High-speed Railway across Dongping WaterwayCable-stayed Bridge, three different erection schemes of upper structural steel girder are analyzed. Themain difference among the schemes is that the wet joints and the prestressed construction time aredifferent. Through the finite element calculation and analysis, the force of the structure in theconstruction process, the force of the bridge, the cable force, the alignment of the bridge, the lateraldeformation in the steel girder installation process and the construction period are compared andanalyzed. After comprehensive comparison, the scheme 3 is finally determined as the optimal scheme.
