摘要： 随着机场综合交通枢纽工程的规划和建设，高速铁路和快速地铁近距离穿越机场塔台引起的车致振动响应受到空管部门的重视，且目前尚无铁路穿越塔台的相关案例和指导标准可供参考。以国内某在建机场综合交通枢纽为研究对象，对250km/h高速铁路和120km/h快速地铁近距离穿越塔台时引起的振动进行分析，并对塔台功能层的振动响应进行评价。研究结果表明：高速铁路通过时，塔台振动主频集中在30~70Hz范围内，电梯间和功能区分频最大振级分别为75.6dB和66.8dB，超过62dB的夜间振动限值；快速地铁通过时，塔台各层振动均未超标；高速铁路和快速地铁同时通过时，塔台车致振动响应产生叠加，电梯间和功能区分频最大振级分别为79.5dB和67.5dB，整体超标率达0.97%~28.2%，以上结论可为高速铁路和快速地铁引入机场枢纽建设工程提供参考和依据。

Abstract: With the planning and construction of the airport integrated transport hub project, it is inevitable that high-speed railways and rapid subway will cross the airport tower at close range. The impact of vehicle-induced vibration on the tower has attracted attention from air traffic control, and there are currently no relevant cases and guidelines for railway crossing the tower for reference. This paper takes a domestic airport integrated transport hub as the research object, analyzes the vibration caused by 250 km/h high -speed railway and 120 km/h rapid subway passing the tower at close range, and evaluates the vibration response of the tower functional layer. The results show that when the high-speed railway crosses, the main frequency of tower vibration is in the range of 30-70 Hz, the maximum vibration levels of the elevator room and the functional area of the tower respectively reach 75.6 dB and 66.8 dB, exceeding the night vibration limit of 62 dB. When the rapid subway crosses, the vibration of each layer of the tower does not exceed the standard. When the high-speed railway and the rapid subway cross at the same time，the vibration response of the tower will be superimposed, the maximum vibration levels of the elevator room and the functional area of the tower control command floor respectively reach 79.5 dB and 67.5 dB，and the overall exceeding rate reaches 0.97%-28.2%. The research results provide reference and basis for subsequent railway construction into airport hubs.
