| 摘 要： | 随着铁路尤其是高速铁路系统的发展，列车引起的振动日益频繁，对邻近建筑及人们生活造成不可忽视的影响．针对铁路交通引起的地面振动问题，利用车辆一轨道相互作用模型，采用有限元法计算得到轨道与路基间的相互作用力，经傅立叶变换后作为地面振动计算的激励荷载．在此基础上计算了高速列车行驶条件下所产生的周围地面振动，并分析了地面振动的一般规律．

| Abstract: | With the developing of the railway,especially high speed train,ground vibration due to railway traffic cause increasingly distress to adjacent structure and annoyance to residents.In this paper,aimed at the problems of ground vibration due to railway traffic,the sleeper-ballast interaction forces are calculated by FEM using train-track interaction model,which can be used as exciting loads for calculating ground vibration after Fourier translation.Based on it,ground vibrations due to high speed railway traffic are calculated,and the law of them is also analyzed. |
