Numerical Simulation of Soft Ground Vibration Caused by High-speed Trains
The soft ground vibration caused by high -speed trains is an important issue which needs to be carefully investigated. In this paper,numerical simulation of soft ground vibration is conducted by using two models; the train-track interaction model and track-ground finite element model. The train-track interaction model is built on basis of the vehicle -track coupled dynamics theory and mainly used to get the excitation forces on track structure and soft ground. As an example ,the typical field test of soft ground vibration caused by high-speed train X-2000 in Ledsgard of Sweden is numerically simulated. The dynamic responses of track -ground model under the low and high train speeds are compared. Large amplification is observed in the ground dynamic response when the train speed is close to the critical value.
