Abstract


With the technical development,the bridge construction is getting more and more exquisite,transformation from the traditional practice to advanced and secure practice. The bridge swivel construction is one of them.The biggest difference from the bridge swivel construction to the traditional construction is that it may transform in the barrier above work as the ashore or near ground work.In order to guarantee the security in the swivel process the bridge,usually avoids the gale weather,swivel speed slowly and so on to solve the problem of the intensity and the structural stability research insufficiently in the swivel process.This article unifies the bridge building of the Olympic Games project in 2008(Liang township - Zhaikou section),carries on the structural design and the stability analysis.This article first has made the detailed discussion from advance the bridge swivel construction technical process and the swivel partial structural design.Then uses the software of bridge doctor establishment Body rotating bridge finite element model,and uses the computer sequencing function automatic control production variable cross-section box beam data.Through computer simulation analysis bridge in permanent load,variable load,temperature load function and different construction stage accumulation element stress,bridge pier reaction and bending moment change rule.Finally,use the MIDAS software to computation and analysis the swivel partial of the bridge’s displacement distortion rule in the horizontal bridge direction and along the bridge direction with the crosswise static Rafale and the longitudinal static Rafale function.The flexible characteristic based on the rigid frame body bridge pier,has not used pillar Liang regarding the non-swivel part to solidify the way the bridge pier to use distyle distyle bridge pier + coping to overcome the disadvantage factor which its displacement brings.In the swivel process,analysis the anti-tilts the flexure condition when the most greatly hung wall and buckling stably before the swivel.
