Study on train vibration influence of Qingdao Jiaodong International Airport
Most of the previous studies on the impact of high-speed railway trains on the vibration of building structures are located on both sides of the line,but there are few studies on the impact of structural vibration caused by the high-speed crossing of high-speed railway main line directly below the building.Taking Qingdao Jiaodong International Airport as an example,the vibration impact of the terminal and auxiliary structures caused by high-speed train crossing is studied,the vibration response of the building structure caused by train wheel rail excitation and train wind are calculated and compared,and the amplitude,distribution characteristics and time history characteristics of the train vibration response of the terminal structure are analyzed.In order to reduce the impact of train vibration,a vertical vibration isolation support is set at the bottom of the column in the south of the central area.The calculation shows that the vibration isolation support can effectively isolate the vibration impact caused by train running.
