| 摘 要： | 由于受照射及大气温差的影响，箱梁温度场是极不均匀的，混凝土结构产生极为复杂的变形。为保证施工质量，适当选择合拢段混凝土的浇筑时间与温度采用合理的施工方法，控制混凝土结构变形，使合拢段安全合拢。

| Abstract: | Because of the effects of sunshine and atmospheric temperature difference,temperature field of box girder is extremely heterogeneous, then concrete structures will emerge complex deformation. In order to guaranteen the construction quality, properly selecting the time and temperature while casting in the closure, adopting reasonable construction method and controlling deformation of concrete structures can make the closure be gathered up safely. |
