Study on the Influence Depth of Subgrade of Airport Runway under Different Loads of Plane
The thickness of the subgrade model has great impact on the frequency when analyzing the fundamental frequency of the runway by the finite element model,and airport runway under different model of plane will has different influence depth of subgrade.In this paper,an airport runway finite element model,which is base on elastic layer system theory,is established to be loaded different model of plane.The results show that the influence depth ofsubgrade under different aircraft types,as well as the relationship curves of the influence depth and frequency.
