| Abstract: | The variation characteristics about the closure section of the bridge's steel box girder caused by temperature are analyzed in this paper. On the basis of measuring system and the measured data analysis, the variation regulation of the reserved closure interval, the space-time variation characteristics of the closure section, and the closure time are discussed. It is effective to instruct the closure process of the steel box girder and has practical value. |
