Study on Fundamental Frequency of Airport Runway Based on Elastic Layered Soil Model

Abstract:

The relationship between fundamental frequency and structural layerof runway is discussed based on a series of ANSYS models. The research results indicate that the coupling effect of runway plates on fundamental frequency could not be neglected. According to the analysis on fundamental frequency of runways of different sizes, an area of 45m times 15m affects fundamental frequency the least. Thickness and strength of the base significantly affects fundamental frequency. Fundamental frequency of runway ranges from6.8Hz to 25.6 Hz.
