以一种简化的方法，分别建立了列车—轨道和路基—土层—建筑物的二维动力相互作用分析模型，计算了列车引起的振动在土层中的传播特性及对邻近建筑物的影响．分析结果与实测资料相吻合，可为进一步研究振动环境控制问题提供参考
In a simplified method, a two-dimensional dynamic interaction analysis model for train-track and subgrade-soil-building is established, and the propagation characteristics of train-induced vibration in soil layers and its effect on adjacent buildings are calculated. . The analysis results are consistent with the measured data, which can provide reference for further study of vibration environment control problems.
