摘要
依据提速线（京沪）上现场测试结果和车桥耦合振动理论，分析了既有线提速后４４ｍ半穿式桁梁桥横向振动问题，结果均表明，提速客车通过该桥横向刚度仍能满足要求；提速货车横向刚度明显不足。同时提出提高横向刚度的几种措施并分析其作用效果。
In this paper ,the lateral rigidity of the half across steel truss bridge with 44 m span in the existing railway line is investigated with both the field test and the vehicle bridge coupling viberation theory.The results show that the lateral rigidity of the bridge is satisfactory while the passenger trains pass through it at raising speed and is lack while the freight trains pass through it at higher speed.Several reinforcing measures are presented and their effectiveness is analysed.
