摘要
通过对某高速公路一16 m空心板梁放张过程中关键截面进行理论分析与应力测试,找出了该类型空心板梁放张过程中关键受力截面的应力变化规律以及空心板底板容易出现纵向裂缝的原因,得出了一部分有益的结论,可以为该类型梁体的施工与设计提供参考。
The work of stress test and theoretical analysis of a 16 m prestressed hollow slab beam during the enlargement process is presented in this paper.Some rules of stress change in critical sections and the reasons of longitudinal cracks are found out from the obtained results and some useful conclusions are given,which provide reference for construction and design of similar type of bridges.
