Measurement and Analysis of Vehicle Induced Vibration Characteristics in the Throat Area of Metro Depot
摘要
Abstract
The train operation induced vibration characteristics in metro depots were studied to provide a data support for the development of the depot covers and surrounding areas.A newly built subway depot was taken as the research object.On site measurements were conducted on the crossover line and adjacent buildings in the throat area of the metro depot.Based on actual measurement data,the source intensity characteristics,vibration source characteristics,vertical vibration transmission law and vibration response of adjacent buildings at the throat area intersection of the vehicle depot were ana-lyzed.The results show that there is only a small difference in the vibration levels for the train passes through the source strength measurement point when entering and leaving the warehouse.The maximum Z-vibration level of the vibration source in the throat area is 78.5dB.The vibration attenuation from the rail to the rail sleeper and then to the structural column is in different degrees.Meanwhile,the vibration amplification occurs during the upward propagation of the throat area vibra-tion from the ground;According to the″Environmental Vibration Standards in Urban Area″,the maximum Z-vibration level of buildings near the throat area does not exceed the vibration limit.关键词
