摘要：
An interaction model between the high-speed maglev train and the elevated guideway is established to calculate dynamic electromagnetic forces, and the finite element model of the ground foundation is built to simulate the ground vibration responses induced by high-speed maglev train. The simulation results of the ground vibration are in accordance with the test results from the previous field test, which indicates that the numerical models are appropriate to simulate the ground vibration induced by the maglev train. The numerical results show that the attenuation law of ground vibration of maglev. transport foundation is similar to that of the wheel-rail transport foundation. The ground vibration responses increase nearly linearly with the running speed of maglev train. However, the attenuation curves have no rebound wave in the 20 similar to 30m distance from the route centre. The vibration acceleration levels of the maglev transport foundation are distinctly less than those of wheel-rail transport.
