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。
According to the experimental data analysis, the environmental vibration caused by the bus running on the test section of the Su-Yu high-speed railway ballastless track has been measured on the spot. The environmental vibration intensity decreases with the increase of distance and increases with the increase of vehicle speed, The main frequency range of environmental vibration is 30 ~ 120 Hz. The distance from the track, the speed of vehicle and the number of cars have no significant effect on the main frequency of vibration. At 31.9 m on both sides of the track, the speed exceeds 104.7 km / h Environmental vibration intensity exceeds GB 10070-1988 requirements, measures to be taken to vibration isolation.
