In this paper, a field experiment was carried out to study train-induced environmental vibrations. During.the field experiment, velocity responses were measured at different locations of a six-story masonry structure near the Beijing. g.ang.hou Railway and along.a small road adjacent to the building. The results show that the velocity response levels of the environmental g.ound and the building.floors increase with train speed, and attenuate with the distance to the railway track. Heavier freig.t trains induce g.eater vibrations than lig.ter passeng.r trains. In the multi-story building. the lateral velocity levels increase monotonically with floor elevation, while the vertical ones increase with floor elevation in a fluctuating.manner. The indoor floor vibrations are much lower than the outdoor g.ound vibrations. The lateral vibration of the building.along.the direction of weak structural stiffness is g.eater than along.the direction with strong.r stiffness. A larg.r room produces g.eater floor vibrations than the staircase at the same elevation, and the vibration at the center of a room is g.eater than at its corner. The vibrations of the building.were compared with the Federal Transportation Railroad Administration （FTA） criteria for acceptable g.ound-borne vibrations expressed in terms ofrms velocity levels in decibels. The results show that the train-induced building.vibrations are serious, and some exceed the allowance g.ven in relevant criterion.

针对地铁列车运行引起的地表振动响应问题,提出了一个数值预测模型。该模型根据移动荷载作用下的动力响应解,把地铁列车运行引起的振动问题归结到计算频率-波数域内的传递函数和频域内移动轴荷载的问题上。传递函数采用三维周期性有限元-边界元耦合的数值模型来计算,移动轴荷载主要考虑为频域内轨道不平顺激励下简化的轮轨接触力。利用此模型计算了北京地铁1号线东单站至建国门站区间地铁列车运行引起的振动响应,并利用现场振动试验数据对计算结果进行了验证。结果表明,此模型具有良好的适用性,可应用于地铁列车运行引起的地表振动的预测。

针对地铁列车运行引起的隧道结构和自由场中的振动响应问题,提出了一个在频率-波数域内的三维周期性有限元-边界元耦合的数值模型,此模型中隧道结构采用有限元法计算,自由场采用边界元法模拟。此模型采用Floquet变换,利用隧道和自由场在隧道轴线方向上的周期性,把无限长的隧道及自由场的网格划分限制在一个基本元内,这样使动力学数值计算的效率大大提高。利用此模型计算了在隧道底板上施加固定单位谐振荷载情况下隧道-自由场相互作用系统的动力响应,结果表明此模型可应用于地铁列车运行引起的隧道和自由场中的动力响应预测。

以北京某新建地铁线路近距离经过某科研单位为研究背景,对现况道路边和实验室内仪器实验台面的环境振动进行了测试和评估;利用了现场实测与数值模拟相结合的预测方法,该方法考虑了建筑结构、实验台在不同频段下的振动衰减或放大作用,并在1/3倍频程频域下与国际通用的精密仪器防振要求进行比较。采用周期性有限元-边界元耦合方法预测了列车对自由场地的动力响应。基于实测振动响应传递比曲线将楼外振动响应折算到实验台面上,以此评价地铁列车振动对精密仪器的影响。研究结果表明:(1)现况道路车流对实验台水平方向振动较大,应采取相应被动隔振措施;(2)当列车低速、匀速通过时,振动对仪器影响较小;(3)车速大于60 km/h匀速通过时,应采用较高级别的减振轨道以确保仪器正常工作。
