高铁客专32m后张法简支箱梁静载实验研究

结合京津城际轨道交通工程3号梁场工程实例,介绍了高速铁路预应力混凝土简支箱梁静载试验的方法和数值分析方法,试验与理论分析表明,梁体静载试验理论分析和计算方法可靠,箱梁刚度和承载能力满足设计要求。

Research on static loading experiment on 32 m post-tensioned method simple box beam of passenger special line of express railway

Combining with the No.3 beam field project intercity track traffic project between Beijing and Tianjin,the paper introduces the experimental methods and numerical analysis method of the prestressed simple box beam's static loading experiments of express railways,and proves by the experiments and theoretic analysis that the beam static loading experiment theoretic analysis and calculation methods are reliable,and the stiffness and the loading capacity of the box beam can meet the design need.
