大型“桥建合一”客运站候车舒适度评价研究

Study of Large-scale Bridge-architecture Composite Passenger Station Comfort Evaluation

针对列车制动启动和高速运行给大型桥建合一客运站带来的振动问题,以某典型客运站为例,从列车运行模式出发,建立站房振动舒适性分析有限元模型,通过时变系统动力积分的方法,得到候车厅典型位置的动力响应曲线,根据《城市区域环境振动标准》对站房进行候车舒适度评价。

Starting from the model of train moving into and out station,this paper focuses on the vibration of large-scale bridge-architecture composite passenger station caused by the braking and starting and high-speed operation of vehicle. Moreover,a finite element model is built for comfortable level analysis of passenger station building. Dynamic integration is used to get the response curves of time-variable system,finally the comfortable level of passenger station is evaluated according to the Standard of City Region Environmental Vibration.
