摘要:文章以实际工程为例,对预拱度的设置、梁体各阶段挠度的计算以及制梁台座拱度的设置进行分析,探讨预制预应力I梁施工过程中相关因素的控制,希望能为不同梁型的公路施工提供参考与借鉴。

关键词:预制I梁;预拱度设置;挠度计算

Abstract: Taking actual engineering as an example, this paper analyzes the setting of precamber, the calculation of deflection of beam body at each stage, and the setting of camber of girder pedestal, discusses the control of related factors in the construction process of precast prestressed I beam, hoping to provide reference for highway construction of different girder types.

Key words: prefabricated I beam; precamber setting; the deflection calculation
