Simulation And Analysis For Environment Vibration Induced By Urban Rail Transit With Ground Line
The environment vibration induced by urban rail transit becomes one of the severe environmental hazards and attracted great attention for researcher at home and abroad.Firstly, on the basis of track irregularity theory, an exciting force function of vibration source induced by ground line train is established.Then, the exciting force acts on the three-dimensional models of rail bearing structure and soil propagation path by utilizing the finite element software.The surrounding environment vibration response caused by train operation is simulated and the numerical results are compared and verified by the field measurement data.Furthermore, the parameter effects of train speed and properties of site soil on environment vibration are studied.The researches show that the numerical simulation in the paper can truly reflect the actual environment vibration caused by urban rail transit with ground line.
