The Key Technology And Benefit Analysis About Curved Continuous Box Girder

With the development of construction engineering, different kinds of the way about building bridge structure appear constantly, curved continuous box girder structure began to be widely used in bridge construction.Therefore, the importance of strengthening project management of rectification process will gradually highlight.The article analyzes the impact about the force situation of Curved continuous box girder as well as the braking force and temperature force, and at the same time it does a simple introduction about the torsion reason, the judgment standard and the deviation rectifying technology about the curved continuous box girder. Then according to the practical engineering data was constructed the finite element model, after that, uses the method of general finite element analysis program to analysis and calculation of operation. Using the data of different parameters, the comparative analysis of curved continuous box girder under the braking force, temperature stress, centrifugal force and other external cause and material, construction and prestress change internal cause change of circumstances.Through the monitoring process for rectifying engineering, with scientific evaluation method and the reasonable solution to prevent and solve the potential problem of curve Beam Bridge, it would make sure the safety operation of the bridge.With the research significance of curve beam bridge rectifying, it can improving the roads safety, increasing the comfort of driving; Short construction time, little influence on traffic, bring social benefits; as far as possible keep disease beam body, reduce social influence in the same time increased economic efficiency, save more construction expenses and make the construction of block curved box girder standardized and have a far-reaching influence.
