吉林市白山大桥连续梁合拢顺序及劲性骨架方案研究

Study on the Sequence of Continuous Beam Collapse and the Rigid Skeleton Scheme of Baishan Bridge in Jilin City

本文依托白山大桥连续梁合拢段施工项目,对连续梁合拢段施工技术进行了分析及研究。详细阐述了合拢段气温变化时轴力计算、降低轴力措施、劲性骨架设计、临时锁定方案、施工配重方案、施工要点等,为其它项目连续梁的合拢段施工提供参考作用。

Based on the construction project of the continuous beam closing section of Baishan Bridge, this paper analyzes and studies the construction technology of the continuous beam closing section. The axial force calculation, the reduction measures of axial force, the stiff skeleton design, the temporary locking scheme, the construction weight scheme and the construction points are discussed in detail in the closed section temperature, which provides reference for the construction of the continuous beam of other projects.
