| Abstract: | Based on Liuxihe long-span brige,using finite element software the simulation model of the bridge at cantilever construction phase is established,and analyed the temperature effect of the box girder,then put forword the impact of stress and deformation to the bridge.Then comparing the experimental data and the theoretical data the correctness of the model calculations is verifyed.Reference for similar bridge construction monitoring can be provided. |
