| 1 | 地铁列车振动对精密仪器影响的预测研究显示文摘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。 | 马蒙 刘维宁 丁德云 Degrande G 刘卫丰 | 2011 | 振动与冲击2011，30，3： | 37 |

| 4 | Experimental investigation of railway train-induced vibrations of surrounding ground and a nearby multi-story building显示文摘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-Guangzhou Railway and along a small road adjacent to the building. The results show that the velocity response levels of the environmental ground and the building floors increase with train speed, and attenuate with the distance to the railway track. Heavier freight trains induce greater vibrations than lighter passenger 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 ground vibrations. The lateral vibration of the building along the direction of weak structural stiffness is greater than along the direction with stronger stiffness. A larger room produces greater floor vibrations than the staircase at the same elevation, and the vibration at the center of a room is greater than at its corner. The vibrations of the building were compared with the Federal Transportation Railroad Administration (FTA) criteria for acceptable ground-borne vibrations expressed in terms of rms velocity levels in decibels. The results show that the train-induced building vibrations are serious, and some exceed the allowance given in relevant criterion. | Xia He Chen Jianguo Wei Pengbo Xia Chaoyi G. De Roeck G.

| 5 | 地铁振动预测的周期性有限元-边界元耦合模型显示文摘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。 | 刘卫丰 刘维宁 Gupta S Degrande G | 2009 | 振动工程学报2009，22，5： | 13 |
| 6 | 地铁列车运行引起的隧道和自由场的动力响应预测显示文摘针对地铁列车运行引起的隧道和自由场动力响应的预测,提出一种计算方法。根据移动荷载作用下隧道及自由场的动力响应解,可以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的轮轨接触力。利用此方法对北京地铁4号线北京大学东门站北侧区间地铁列车运行引起的隧道和自由场的振动响应进行了预测,并比较了普通无碴轨道和钢弹簧浮置板轨道的动力响应。结果表明:此方法具有很好的适用性;浮置板轨道具有很好的减振作用,但对低频段振动没有效果。 | 刘卫丰 刘维宁 GUPTA S DEGRANDE G | 2010 | 工程力学2010，27，1： | 7 |
| 7 | Prediction of vibrations from underground trains on Beijing metro line 15显示文摘The impact of vibrations due to underground trains on Beijing metro line 15 on sensitive equipment in the Institute of Microelectronics of Tsinghua University was discussed to propose a viable solution to mitigate the vibrations.Using the state-of-the-art three-dimensional coupled periodic finite element-boundary element(FE-BE) method,the dynamic track-tunnel-soil interaction model for metro line 15 was used to predict vibrations in the free field at a train speed of 80 km/h.Three types of tracks(direct fixation fasteners,floating slab track and floating ladder track) on the Beijing metro network were considered in the model. For each track,the acceleration response in the free field was obtained.The numerical results show that the influence of vibrations from underground trains on sensitive equipment depends on the track types.At frequencies above 10 Hz,the floating slab track with a natural frequency of 7 Hz can be effective to attenuate the vibrations. | 丁德云 刘维宁 GUPTA S LOMBAERT G DEGRANDE G | 2010 | Journal of Central South University2010，17，5： | 6 |
| 8 | Prediction of vibrations induced by trains on line 8 of Beijing metro显示文摘This paper mainly discusses the problem of ground-borne vibrations due to the planned line 8 of Beijing metro which passes under the National Measurement Laboratory.A lot of vibration sensitive equipments are placed in the laboratory.It is therefore necessary to study the impact of vibrations induced by metro trains on sensitive equipments and important to propound a feasible vibration mitigation measure.Based on the coupled periodic finite element-boundary element (FE-BE) method,a 3D dynamic track-tunnel-soil interaction model for metro line 8 has been used to predict vibrations in the free field induced by trains running at variable speeds between 30 km/h and 80 km/h.Four types of track structures commonly used on the Beijing metro network have been considered:(1) high resilience direct fixation fasteners,(2) Vanguard fasteners,(3) a floating slab track and (4) a floating ladder track.For each of these track types,the vibration isolation efficiency has been compared.The results of the numerical study can be used to predict vibrations in nearby buildings and to decide upon effective vibration countermeasures. | De-yun DING Shashank GUPTA Wei-ning LIU Geert LOMBAERT Geert DEGRANDE | 2010 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2010，11，4： | 4 |
