Ground Vibration Induced by Maglcv Train Passing through Tunnel
An interaction model between high-speed maglev train and guideway is established to cal -culate dynamic electromagnetic forces ; and the finite element model of the tunnel and soil foundation is built to calculate ground vibration. Numerical results show that ground vibration induced by high -speed maglev train passing through the tunnel mainly contains some low -frequency responses ; attenuation laws of ground vibration are similar to that induced by the wheel -rail train ,the rebound area of ground vibration appears near 20m distance from the route center. In general,vibration acceleration levels around the maglev tunnel are quite small. When a full-load maglev vehicle passes through the tunnel at speed of 200km/h, the vibration acceleration level of right above of the tunnel is only 66dB. When the running speed of maglev train increases by 50km/h,the vibration acceleration level rises by 6 to 8dB.
