Numerical Prediction of Subway Induced Vibrations: Case Study in Iran-Ahwaz City

M.S. Pakbaz, R. Mehdizadeh, M. Vafaeian and K. Bagherinia

Abstract:
Traffic jams in big cities have made necessary the need for use of underground metro trains more than ever. However, movement of trains with appropriate speed in between stations produces vibrations that may sometimes be disturbing for people living in the region. Actual measurement of vibrations in Tehran metro is used to predict numerically the vibrations created by passage of trains in the surrounding surface in city of Ahwaz metro under construction. With comparison of the ground surface vibrations in different stations along the Ahwaz metro route, it is concluded that in general the level of vibrations in Northeast part of the route are higher than the Southwest part, this due to the presence of the rock formation in the Northeast part. The calculated vibrations in the Northeast part are higher than the allowable, therefore, appropriate measures should be taken to decrease these vibrations. Also, According to the result of this research, with twice increase in speed of train, the ground surface vibrations increase by 4 to 6 dB which is consistent with other researches. According to this research there is no distinct relationship between vibrations and depth of water table. It is concluded that probability of the resonance occurrence along the Ahwaz metro is very low.
