Abstract:

Urban rail transit has developed rapidly in recent years, underground lines occupied a considerable proportion of all the lines, accounts for about 70% of the total line length. The main environmental impact of the underground line is environmental vibration, therefore, predict the environmental vibration impact of the running train is the key of underground line environmental impact assessment. This paper systematically compare and analyze the vibration prediction model in the state environmental protection standard—“Technical Guidelines for Environment Impact Assessment of Urban Rail Transit”(HJ453-2008) and the local environmental protection standard of Beijing—“Code for application technique of metro noise and vibration control”(DB11/T 838-2011). Combined with the subway vibration impact in the process of actual operation, analyze the respective advantages and disadvantages of this two vibration prediction model, and putting forward the corresponding opinions and suggestions for the revision work of national standard and Beijing local standard in the future.
