Numerical study on high-frequency effect of rail corrugation on subway-induced environmental vibrations

Analysis and intelligent prediction of subway train-induced vibration in the building with pile foundation

“…The results show a slight fluctuation in the predicted values from 4 Hz to 25 Hz compared to the measured values. This may be due to the frequency range of 4 Hz to 25 Hz being the dominant frequency for the train-induced vibration of the buildings, and the train-induced vibration is also closely related to the vehicle, track, and the site conditions[19], which may lead to the fluctuation of the measured values in engineering practice. However, the onethird octave vibration acceleration levels predicted by the GA-BP model are overall similar to the measured values, which proves that it is feasible to use the GA-BP model to predict the train-induced vibration of the buildings with pile foundation adjacent to the subway line.…”
