| 摘 要： | 本在现场试验的基础上，利用频谱分析方法，得出由于地铁列车振动而起的轨道振动加速度的数定表达式，根据车辆系统振动简化模型，建立了正确的模拟轮系的运动方程，从而推导出地铁列车振动荷载，为进一步分析列车振动荷载作用下地下结构动力响应打下了基础。

| Abstract: | On the base of the tests carried out at the subway,the deterministic formulas for vibration acceleration of track are derived by using the vibration model of vehicle system.The problem of identifying dynamic load of subway train is solved and it turns to create favorable conditions for further studying the dynamic response of structure subject to the load of passing train. |
