摘　　要：重载铁路运输是铁路货运发展的方向。由于重载铁路列车轴重大、运输频次密、列车长度大,振动已成为重载铁路运营期的主要环境污染形式之一。与高速铁路引起的环境振动相比,重载列车运行引起的环境振动强度更高,峰值频率更低,峰值持续时间更长。开展轴重、运行速度、地质条件对环境振动影响的研究,构建合理准确的预测方法,对重载铁路环境振动的预测和防治具有重要意义。The heavy-haul railway is the mainly developing trend for rail freight transportation.As its heavy axle,high transportation frequency and large train length,ground vibration induced by heavy-haul railway has been one of the main forms of the environmental pollutions.Compared with high-speed railway,environmental vibration generated by heavyhaul railway is characterized as the higher vibration levels,the lower dominant frequency and the longer duration time.It is important to study the effects of axle loads,speed,and geologic conditions on the environmental vibration and to introduce the reasonable and exact prediction method to predict and prevent environmental vibration induced by heavy-haul railway.
