The Analysis And Design Study Of Single Pillar And Big Cantilever Light Railway Station

As quickly developing of our country's building,the traffic jam is the serious problem in city.A lot of advanced characteristics such as large transportation burden,high speed,low power-wasting,little investment,no pollution,safety,on schedule and so on which light railway have make itself to be the necessary choice for ChongQing which is mountain city.The design method of single pillar and big cantilever station with Shiziping station is analyzed in this paper.The length of cantilever beam is 10 meters and the height of this station is 22 meters.The height of track is 14 meters.The length of this station is 120 meters.The seamless design will be the best method when take consideration of the using and dynamic property.Thus cannot but there are large tempreture stress in the station.So it is very important to analyse the regulation of tempreture stress distribution.The station of light railway is different from familiar architecture and bridge.The dynamic property of station when train pass through the railway is an important factor which effect the quality of the station.This paper analysed the dynamic property of station when train pass through the rail.There are some conclusions below.â‘ It is more safty when make the static analysis if adopt the more safty thoery and regulate after comparing the building code with the bridge code.â‘¡There are two measures to control the tempreture stress that is to say they are restrict and loosen.From structure system,we can increase the calculated length of end post(increasing the depth of embedment)to decrease the lateral rigidity of pillar.This method is to decrease tempreture stress by unbracing.On the lengthwise direction,try to decrease the rigidity of the structure.To put the full-length reinforcing steel bar along the lengthwise direction to resist tempreture stress.Adopting the compensating concrete to improve the creep of concrete.â‘¢From the analysing,we can see that the lateral deformation control the structure. This paper analysed the dynamic property of station when shifting load applied on station.The conclusion indicate that the vertical rigidity is not enough.So it is neccery to improve the dynamic property by increasing the vertical rigidity,that will decrease the magnitude of dynamic displacement and acceleration.The reasons which result of station libration have to do with the smooth degree of rail.The bigger simple harmonic force's frequence is,the bigger Sperling.So we should try our best to decrease the frequency of force to improve the degree of coziness.
