Abstract
Using Transit-oriented development over-track buildings have been rapidly expanding on Chinese subways due to its convenience, however the excessive indoor vibration and noise within over-track buildings has been a cause of concern for some time. A prediction method considering soil-pile-structure dynamic interaction based on the three-step approach is proposed to study train-induced vibration of over-track buildings. A case study is carried out of over-track buildings on a subway transfer station in Chengdu, China. The simulation results indicate that, the highest indoor vibration of a superstructure is 84.0dB without vibration reduction measures, which seriously exceeded the criterion limit, train-induced vertical and longitudinal building foundation vibrations are quite large and relatively the same, lateral vibration is at a minimum. Six combined comprehensive vibration reduction measures are analyzed by numerical simulation, field measurements show that ground and local building vibration in a Line 3 transfer station are not exceeded.
