详细介绍了胶济线K2 47+2 5 7上承式钢桁梁的振动试验成果 ,并从该桥自振特性 ,竖、横向振动振幅 ,轮轨水平力及脱轨安全度等诸方面对测试成果进行分析 ,阐述了列车通过该桥的安全性 ,并对客。
This paper presents the vibration test results on the over-type steel truss bridge of K147+257 in the Jiao Ji Railway, and Analyses the results from the view point of the bridge characteristics of the free vibration, the vertical and transverse amplitudes of the bridge, the horizontal forces between the rail and wheel and the safety of the derailment. The suggestion of the allowable velocity for the passenger and freight vehicle pas sin g through the bridge was given.
