摘要
首先对新广州站站房结构基本情况进行介绍,然后给出了一种目前通用的舒适度评价方法,并在此基础上对新广州站在列车通过时的振动舒适度进行验算。本文给出了列车振动激励力时程的计算方法,以此来计算列车高速通过时的振动响应,并从楼面响应最大值、典型变形形式、楼面响应沿横轨向和顺轨向分布、典型响应时程等几个方面对计算结果进行分析,最后给出了计算结论和舒适度评价结果。
A main introduce to the structure of New Guangzhou Station is carried out,and the vibration serviceability with a commonuse evaluation rules is given after that.Then the method to get the vibration forces of the train wheels to the orbit is detailedly presented.The response of the New Guangzhou Station waiting hall＇s floor under the vibration of running train is calculated with a timehistory finite element analysis,and the vibration serviceability is evaluated after that.Detailed analysis is done on the following aspect including the maximum response in the floor,classical deformation pattern,the distributing form of response in the transverse orientation,classical response history etc.,from which some valuable conclusions are derived out.
