In order to provide a calculation method for the design of the sandwich panel structure, a threedimensional finite element model of the sandwich panel structure of multilayer elastic foundation is adopted by ANSYS. At the same time, the finite element model is utilized for calculating the mechanical response of the aircraft used in the typical pavement structure. The results show that the type of face plate has little effect on the mechanical response, and the contact status between the pavement and the base course greatly affects on it. The contact coefficient increases from 0.01 to 10, and the deflection of the single and double plates decreases by 17.2% and 9.9% respectively. At the same time, the tensile stress under the base is reduced by 21.7% and 27.1%. This shows that the improvement of the contact status between the pavement and the base is fatal. Finally the bearing plate test and pass test are completed. The experimental results verify the correctness of the finite element model, and provide the analytical method for the similar pavement structures.
