Subway Train-Induced Noise And Vibration In Building: Predictions And Measurements

摘要

Urbanization ensures that noise and vibration from rail and metro lines will continue to be an important field of research as structures coexist with nearby rail lines. The transmission of train-induced noise and vibration through building remains an active field of research. This ongoing research is largely due to the complexity of modelling the transmission of broadband vibration through the soil, into the building's foundation, and within the building itself. There are numerous approximate methods, empirically-derived models, and detailed finite and boundary element approaches available to predict train-induced vibration levels within buildings; however, the uncertainty associated with these predictions remain large, and few have been extensively evaluated with measurements.
