Abstract The visco-elastic artificial boundary was analyzed to be suitable for the layer rock. Taking the Qingdao metro line #3 as the studying subject，the computation model was constructed to study the effects of rock elastic modulus，tunnel depth as well as tunnel lining thickness on the rock environmental vibration response induced by the metro train. The results show that the variations of rock elastic modulus at different depths generate different effects on the rock environmental vibration response. There is only one amplification zone of vertical acceleration at the free surface of rock environment with great elastic modulus，where the acceleration amplification zone is at the tunnel upward of free surface. The vibration effects of metro trains on free surface increase with the decrease of tunnel depth. The tunnel lining thickness has few effects on the rock environmental vibration response induced by the metro train.
