Field Monitoring and Analysis on Dynamic Responses of Taxiway Foundation Subjected to Aircraft and Subway Loadings
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.
