摘要 随着运行速度的提高,高速列车对环境振动的影响变得更为明显。列车造成的振动会进一步传递至上部结构,影响上部的结构安全性和人员舒适性,需要在设计时予以解决。本文对高速列车通过北京大兴国际机场时航站楼的结构振动响应进行了计算分析,对车致振动的幅值大小、分布特点、时程特点等规律进行了研究,并重点研究了轮轨激励和列车风各自造成的振动影响。结果表明,对于北京大兴国际机场这种梁板结构地下站场形式的封闭空间,当列车速度达到350km/h时,列车风引发的列车振动响应明显,设计时需充分考虑。 With the increase of train speed, the environmental vibration becomes obvious. The vibration induced by train is transferred to superstructure, and the structural safety and serviceability are affected, which should be settled in design. The vibration responses of terminal of Beijing Daxing International Airport are calculated, the vibration amplitude, distribution and time history characteristic are studied, the vibrations caused by air flow or wheel-track excitation are analyzed separately. The results show that, when train speed is 350km/h, the vibration induced by train air flow is very significant for the non-tunnel structure of Beijing Daxing International Airport, which should be considered in design.
