Fundamental research of train -induced vibration based on measurement at railway tunnel

摘要

Train-induced vibration is measured at a subway open-cut tunnel to discuss the influence of vibration on the spalling of tunnel concrete lining. This paper presents and discusses measurement results. At the same time, propagated vibration is calculated by 2-D FEM analysis by inputting the measured acceleration near the track. As a result of that, the calculated results are found to have the similar tendency to the measurement data. It is concluded that the wave propagation is discussed by using this numerical analysis method.
