Abstract:

To explore the transfer relationship between the single wheel load applied on the surface layer of airport rigid pavement and the perceived load on the base top, and provide theoretical basis and reference for the inverse calculation
of this process, firstly, a three-dimensional finite element model of the airport rigid pavement was established using
ABAQUS software. Secondly, taking B737-800 as an example, the influence of changes in runway structural parameters on the transmission process under different load capacities was calculated. Finally, different aircraft load
conditions were designed for different landing gear types, and the load transfer process was compared between
those with the same landing gear type but different landing gear spacing and those with different landing gear types
but similar landing gear spacing. The calculation results showed that the cushion layer elastic modulus and the surface layer thickness have the most significant impact on the load transfer process. Under different conditions of
cushion layer elastic modulus and surface layer thickness, the maximum difference in perceived load at the top of
the foundation was 20.36% and 8.49%, respectively. When the single wheel load is fixed and the form of the main
landing gear wheel group is the same, the perceived load at the base top decreases with the increase of the main
landing gear spacing. When the load superposition of the main landing gear wheel group on the other side is weak
enough to be ignored, the load sensing relationship was basically the same under different wheel group configuration.
