| Abstract: | HuangLingDong bridge is deck-type arch bridge, whose main span is 152 metres and arch rid is stiffening steel pipe frames concrete box structure. The paper describes the methods of making grind centre, grind gap and balance pier, and highlights the impact of the force performance of steel pipe skeleton and concrete creep on bridge swing construction, analyzes the construction of cable-control, construction force and deformation monitoring of stiffening frames and temperature effect of stiffening skeleton box-arch. It may provide reference for bridges of same type. |
