Abstract
It is common knowledge that the increase in train speed may cause the increased dynamic action induced by the train on track and ground surface. This occurrence is especially serious under the high speed operation. Studies have shown that when train speed reaches or exceeds some critical velocities, there would be surface waves induced by high speed trains causing strong vibration of the track structure. In order to study the mechanism of the strong vibration of the track structure caused by high speed train, the analytical method for dynamic analysis of the track structure is described by establishing the continuous elastic foundation beam model of the track structure, the characteristics of the ground wave induced by high-speed train and the strong vibration of the track, and the influence of the track stiffness on track critical speed and the track vibration are investigated by the analytical method in this chapter.
