Mechanical Analysis on Incremental Launching for the Steel Box Girder

Abstract:

Houdingxiang No. 3 Bridge is a 4-span steel box girder bridge. After the incremental launching construction, the bridge has to be lowering to the support bear, the lowering construction is divided into three stages. At first the launching equipment is used to lower 80cm, the next the jack with load capacity of 180 tons is used to lower 110cm, finally three-direction-jack with load capacity of 200 tons is used to lower 20cm. mechanical analysis on lowering the bridge used jacks with the load capacity of 180 tons and 200 tons is respectively carried out by FEM software ABAQUS, and the result shows that this kind of lowering technique is safe and reliable, it meets the construction demand.
