Research On Reinforcement Methods Of Lateral Deviation Disease For The Curved Continuous Girder Bridge

With the development of high grade road and urban modernization, curvedcontinuous girder bridge was widely built. Especially in recent years, as the city viaductbridge developed, many overpass bridges were needed to build. During high grade roadconstruction process, curved continuous girder bridge is the only reasonable bridge typewhich can connect different direction traffic. However, in recent years, many curvedcontinuous girder bridges show lateral deviation phenomenon. Seriously affect thesafety of the bridge structure operation.Based on investigation and research typical disease of curved continuous girderbridge and the common reinforcement methods, first of all, Lateral deviation reasons ofcurved continuous girder bridge are analysed, then we set up the FEM to analyze theinfluence of girder lateral deviation to structure mechanical properties rely on specificengineering project, then put forward the common reinforcement methods for curvedcontinuous girder bridge,Again put forward the measures to prevent lateral deviation.At last set up the FEM to analyze the common reinforcement methods application effectrely on specific engineering project. The main conclusions of the paper are as follows:â‘ The main lateral deviation reasons of curved continuous girder bridge aresupport mode, temperature load, shrinkage and creep of concrete, vehicle load andprestressed steel beam.â‘¡Set up the FEM to analyze the influence of girder lateral deviation to structuremechanical properties rely on specific engineering project.â‘¢The common reinforcement methods for lateral deviation disease of curvedcontinuous girder bridge was lateral spacing device, girder jacking translation reductionand reinforcement the single column pier, The main prevention methods for lateraldeviation disease of curved continuous girder bridge was design and construction, Setup the FEM to analyze the common reinforcement methods application effect rely onspecific engineering project.
