摘要
以高速列车运行时的轨道-地基系统为对象,将轨道-地基系统简化为半无限地基及成层地基上的Winkle梁模型,对高速移动荷载作用下梁-地基系统的协同工作进行了分析,得到了轨道与地表面的动力响应。
The train track-ground interaction is analysed under the moving load on the track and the induced ground vibration. The track is modeled by a bending beam. The ground is modeled by both a half-space and layered stratum on rigid based. First, the ground characteristic is studied by the frequency-wave number domain for the wave propagation. Secondly the loading on the ground interacted with the track is evaluated. The presented results make useful basis for predicting the dynamic response of track-ground systems under high speed moving load.
