主　　题：field measurement metro depot peak frequency vibration acceleration environmental impacts 

摘      要：This paper presents a study of the characteristics of a railway vibration at three key sections containing different track structures in a metro *** results show that the vertical and horizontal vibration acceleration levels are proportional to train *** Z-weighted vertical acceleration levels obtained showed that the vibration source strengths at the ballast foot of the testing line and the throat area were very *** vibration attenuation at the repair line was larger than that of the testing *** the throat area,the peak frequency of vibration obtained at the ballast foot(2.5 m)could be shifted to a lower frequency band by using polyurethane sleepers instead of standard concrete *** sleepers can help to reduce vertical vibration in a frequency band of 0-10 *** vibration levels would satisfy the limits given in the ISO2631-2-2003(2013)for any location more than 5 m away from the source at the testing line and 2.5 m away from the source at the repair line and throat area.
