铁路的运行振动对结构物以及站内旅客舒适度的影响不可忽视.采用有限元计算方法,推导了传统三维黏弹性边界的等效三维六面体单元,并对列车振动对杭州萧山国际机场三期结构的影响进行了研究.得到了列车通过时的航站楼最大振动速度值,相关结果满足结构振动响应安全性的要求,验证了结构设计的合理性.
Abstract：The influence of the running vibration of the railway on both the structure and the comfort of the passengers in the station cannot be ignored.The equivalent three-dimensional hexahedron element of the traditional three-dimensional viscoelastic boundary is derived by using the finite element method,and the influence of train vibration on the structure of Hangzhou Xiaoshan International Airport(Phase III)is studied.The maximum vibration velocity of the terminal building when a train passes through is obtained.The relevant results not only meet the requirements for the safety of structural vibration response but also verify the rationality of the structural design.
