Abstract

To further study vibration propagation induced by the heavy-haul train in the seasonally frozen area,this paper examines the world’s largest heavy-freight railway-the Daqin Railway.The vibration accelerations of the embankment and foundation under the operation of the trains are measured during summer、autumn and winter.It is shown that with increasing axle weight and train speed,the peak and mean values of the acceleration increased.When the horizontal distance between the measuring point and the shoulder increases,the acceleration characteristic value decays rapidly.The vibration acceleration attenuated the most from the shoulder to the embankment footing,and the vibration attenuation trend is slowing down when the distance is 5 m away from the shoulder.The increase of train speed will increase the vibration amplitude,but when the vehicle speed increases to about 90 km/h,the change of speed has less influence on the vibration acceleration amplitude.The water content of soil layer in summer and autumn has little effect on surface vibration.The presence of surface frozen soil layer increases the overall stiffness of the embankment and the site,and the acceleration is 10%—26% greater than that of the unfrozen period with the wider acceleration spectrum and high-frequency components.
