摘要：

Many track factors give effect to the vibration induced by the train. F,ail unevenness is one of the factors that affect more influence. With the running of the train, the rail unevenness becomes more and more severity. And the servicing work should be done in order to maintain the safety of the rail. In this paper, firstly, a space due to underground moving loads is adopted as the model of the train moving in the subway. Based on the general dynamical response expression of a point in the spatial object due to train loads, combined with transfer matrix method and numerical computation, the dynamic response of a point in the ground surface of tunnel is given, and the effect of different level rail unevenness to the dynamic response of ground are calculated and analyzed in time domain and frequency domain.
