ANALYSIS OF VIBRATION EFFECTS OF ELEVATED LIGHT RAIL TRAIN THROUGH SHENZHEN NORTH RAILWAY STATION

To realize the design objective of no transit, the elevated light railway Line 4 and Line 6 go through Shenzhen North Railway Station.The vibration due to light railway acts on the railway station building directly, and the other parts of the station building.And it will maybe influence the comfort level of the passengers in the waiting hall and the service performance of additional facilities in station.In the station structural design process, the dynamic responses of vehicle-building structure couple system for Shenzhen North Railway Station under the action of light railway Line 4 and Line 6 were studied.The vehicle brake forces time histories were acted on the station building structure, considering the train irregularity and the cases of single train braking, double train braking and 4 Lines braking.The analysis of vibration was focused on the acceleration response of station building.The results showed that vibration effects could meet the requirement of passengerscomforts.
