Abstract：Here, the semi-analytical finite element method was used to establish a train-track-subgrade interaction model considering dynamic interaction between train and track with the linear Hertz relation and coupling effects between track and subgrade with the dynamic balance method.Under the excitation of track irregularity, subgrade reactions were calculated during train running along railway.Then, subgrade reactions were taken as input of the model to solve environmental vibration along railway established using the finite element software ABAQUS to solve environmental vibrations of sites along railway during train passing through.Finally, environmental vibration detection data between interval stations along a certain urban rail line in Beijing were used to verify the corresponding calculation results.It was shown that the established calculation method is effective; this calculation method is valuable to evaluate environmental vibrations of sites along existing lines and planned ones.
