In order to study the bearing performance of the new prefabricated airport pavement panel (PAPP) structure, a three-dimensional finite element model (3D-FEM) of “square PAPP – stratum” was established based on ABAQUS finite element analysis platform, and then the mechanical and deformation performance analysis under single wheel various limit load positions was carried out. The research showed that the influence radius was less than the side length R of the panel, The maximum opening or minimum compression of the joint under single wheel conditions was very small, and the maximum principal stress value of the precast concrete panel was an important key control factor for the ultimate load-bearing capacity. Under the action of vertical load, the tenon and groove joint connects multiple independent prefabricated panels to form a whole through mutual occlusal action. The research work provided a useful reference for the design and construction of PAPP.
