浅谈预应力混凝土连续刚构挂篮设计及施工工艺

石马河特大桥主桥上部结构为四跨预应力混凝土连续刚构。该文介绍了该大桥主桥悬臂梁段挂篮悬浇施工工艺的详细计算分析和研究。通过实践得出该设计的挂篮悬浇混凝土施工对于石马河特大桥这样的混凝土连续钢构桥来讲是合理的,对实际施工方案的研究设计具有一定的指导意义。

Elementary Discussion on Form Traveler Design and Construction Technology of Prestressed Concrete Continuous Rigid Frame

The upper structure of the main bridge of Shima River Overlarge Bridge is 4-span prestressed concrete continuous rigid frame.The article introduces,calculates and analyzes the form traveler pouring construction technology of the cantilever beam section of this bridge.Its practice shows that it is reasonable to design this form traveler pouring concrete construction for such a concrete continuous rigid frame bridge of Shima River Overlarge Bridge,which has some guiding meanings for the design of the practical construction schemes.
