The Vibration Influences Of The Stations From The High Speed Trains Passing By On Platform

With the continuous progress of Chinese urbanization, the mobility of peoplebetween cities is increasing. Intercity rails, convenient, green, safe and comfortabletransport means with large carrying capacity have been developed in many cities inChina. The inter-city railway stations are generally in the form of elevated station inour country and the loads are mainly shared by the framework structure and bridgestructure. When the trains go through the station with high speed, the vibration causedby them will, in certain degree, influences the station structure and passengers’comfort. Contemporary researches about elevated station are mainly focus on thesubway hall. The study about the whole station is insufficient. In this paper, basing onthe study of Ronggui Station on guangzhou-zhuhai intercity railway line, the vibrationinfluences of the high speed trains’ passing by on station are discussed under threedifferent structure models: Canopy-Bridge-Frame、Canopy-Bridge、Bridge-Frame.The main research works are as follows:（1）Reviews of the characteristics of the inter-city railway, the development ofinternational and domestic intercity railways and the introduction of the form ofdomestic elevated stations and their advantages and disadvantages.（2）Theoretical basis of this paper from Theory of Finite Element DynamicAnalysis and ANSYS software.（3）Discusses about the vibration influences of the stations from the passing byof the high speed trains, international and domestic evaluation criterion about thevibration influences, dynamic load simulation and the basic data about the trains ofguangzhou-zhuhai intercity railway line.（4）Discusses about the Vertical load-time curve of the trains in the speed of200km/h、150km/h and100km/h. The frequency and damping parameters are studiedrespectively under the three different structure model.（5）Basing on the maximum displacement and acceleration of the station, facingdifferent speed of train and under different kind of structure and considering theinfluence of vibrating load on structure under different speed, I analysis the role offrame structure and Canopy structure in the station and the influence of the passing byof high speed train on people in the station hall.
