摘要
以列车运行时的轨道 -地基系统为对象 ,将轨道 -地基系统简化为成层地基上的 Winkler梁模型 ,对移动荷载作用下成层地基的动力响应进行分析 。
The train track ground interaction vibration due to a speedy moving load on the track and the induced ground vibration transmission alongside are analyzed. The track is modeled with a Winkler bending beam on the ground that is modeled with stratum on rigid base. The dynamic response of the ground base under a moving load is obtained. The findings make the useful basis for predicting the case of train induced vibration.
