摘　　要：为了探究飞机滑行荷载与下穿地铁运行荷载联合作用下机场滑行道道基的动力响应,对某濒海软土机场一条滑道实施实时监测,在地铁线临近穿过滑行道的位置布置加速度传感器,以获取机场滑行道地层动力响应信号。通过分离响应信号获得地铁荷载所对应长、短周期频率的响应信号,在频域上对地铁长、短频率信号进行幅值对比,分离出地铁与飞机的动力响应主频率。结果表明,飞机的动力响应主频率为5~30 Hz,地铁的动力响应频率主频率为30~60 Hz,飞机滑行荷载对机场滑行道产生的动力响应是地铁穿行引起的动力响应的6倍以上。In order to investigate the dynamic response of the airport taxiway base under the combined excitiation of aircraft taxiing load and underpass subway running load.Based on the real-time monitoring of a taxiway in a coastal soft soil airport,acceleration sensors were placed near the subway line crossing the taxiway to obtain the dynamic response of the taxiway.The response signals of long and short period frequencies corresponding to subway loads are obtained by separating the response signals,and the main frequencies of the dynamic response of subway and aircraft are separated by comparing the amplitude of the long and short frequency signals in the frequency domain.The results show that the main frequency of dynamic response of aircraft is 5‒30 Hz,and that of subway is 30‒60 Hz.The dynamic response produced by the aircraft taxiing load to airport runway is more than 6 times that produced by subway crossing.
