无碴轨列车运行引起的环境振动影响评价
|
摘要
对遂渝高速铁路无碴轨道试验段客车运行引起的环境振动进行了现场实测,根据实验数据分析得知:环境振动强度随距离增大而减小,随车速增大而增大,但车厢数量对环境振动强度影响不明显;环境振动主要频率范围为30～120 Hz,距轨道距离、车速、车厢数量对振动主要频率影响不显著;在轨道两侧31.9 m处,速度超过104.7 km/h列车环境振动强度超过GB 10070-1988要求,须采取措施隔振。
Through measurements of the field vibration induced by trains operation on the Suiyu ballastless track,a lot of acceleration time-history data were obtained.Based on the experimental data,the analytical results suggest that environmental vibration intensity decreases as the rail distance increases,and increases as the train speed increases,but the influence of train carriage numbers on vibration intensity is not obvious.The environmental vibration main frequency range is between 30 Hz to 120 Hz,the influence of distance to rails,speed of train and train carriage numbers on main frequency is not obvious.The environmental vibration levels of train speed over 104.7 km/h exceed the standard requirements given by the Chinese Code for Urban Environmental vibration(GB 10070-1988).It is essential to take the vibration isolation measures in these areas.
