Abstract Based on wavelet transform，a method of time domain for 3D dynamic finite element method (FEM) of tunnel entrance was introduced；and then a model of FEM was established. The dynamic response properties of tunnel¢s entrance with varying surrounding rock mass were analyzed under the vibration loading of the elevating train. The time-response laws for the entrance of tunnel were obtained. The obtained results have important significance for further analyzing dynamic stability of tunnel by reason of the speed-elevated train.
