有限元在悬浇挂篮结构计算中的应用

摘要

小绥芬河特大桥连续梁桥采用(40+64+40)m三跨预应力混凝土箱梁,箱梁2#~7#块采用挂篮悬臂浇筑的方法进行施工,为保证施工期间挂篮能够安全工作,重点对挂篮的主要构件进行了计算分析,采用传统力学方法与有限元方法相结合解决了该挂篮相关构件的计算问题,计算结果表明,挂篮结构的主要构件均能够保证安全工作.%the Suifenhe bridge of continuous girder bridge with(40+64+40)m three span pre-stressed concrete box girder, box girder 2#~ 7#block by means of the hanging basket cantilever con-struction, to ensure the construction period of the hanging basket can work safety, In this paper, the main components of the hanging basket are calculated and analyzed, and the traditional mechanical method and the finite element method are combined to solve the calculation of the related components of the hanging basket, the calculation results show that the main components of the hanging basket structure can ensure the safety of work.
