岔口河特大桥连续梁现浇支架设计技术

Design of Bracket for an On-site Casting of Continuous Girder of Extra-large Bridge over Chakou River

介绍了岔口河特大桥连续梁现浇支架的地基处理技术,以及现浇支架全部的设计计算过程,采用大型通用有限元软件ANSYS对重点部位进行了数值模拟,并详细阐述了岔口河特大桥连续梁支架设计计算方法,和支架预压方案,为类似的相关支架工程做参考。

This paper introduces the processing technology of the foundation for the bracket of on-site casting of continuous girder of the extra-large bridge over Chakou River,and the overall design and calculation process of on-site casting bracket.A large finite-element Program of ANSYS is applied to give a numerical simulation to key sections.And lastly,this paper expounds in great detail the design and calculation method and the preloading scheme for the bracket of continuous girder of the extra-large bridge over Chakou River,which provides some references to similar bracket projects.
