Based on the Kirchhoff thin plate theory, a three-dimensional spatial mechanical model of the subgrade pavement with an infinite elastic plate on the orthotropic saturated foundation in the rectangular coordinate system is established, and the differential equations under a moving harmonic load are derived. The partial differential equations are solved by using coordinate transform and Fourier transform, and the analytical solutions of the dynamic responses of the plate and foundation are obtained. A three-dimensional spatial finite element model of subgrade-pavement is established by ABAQUS finite element software. The correctness of the method is verified by comparing the theoretical solution with the finite element solution. The influence of foundation parameters on plate displacement and vertical normal stress of soil is further studied. The results show that considering the orthogonal anisotropy of saturated soil, the dynamic response of subgrade-pavement slab interaction can be described more accurately.
