Abstract

In view of the problems caused by rigid pavement discontinuity at airports, a finite difference numerical analysis model was established considering pavement structure, joint, soil foundation, and the discontinuity body, and the influence of discontinuity size on pavement under different aircraft load positions and joint load transfer efficiencies was studied. The influence of discontinuity on the service life of pavement was analyzed by comparing Chinese and foreign codes. The results show that the bending of airport pavement structure caused by discontinuity is obviously affected by the temporal and spatial effects of wheel loads, and different displacement modes will be induced by discontinuity when the aircraft is located at different positions on the pavement. The bending tensile stress caused by wheel load in the upper part of the discontinuity area can reach two times that in the continuity area. The combined action of landing gear multi-wheel load and pavement discontinuity can significantly increase pavement stress, which leads to serious discontinuity damage. Improving the joint load transfer capacity has a positive effect on improving the influence of pavement resistance to discontinuity, and the initial discontinuity of pavement has the most obvious influence on its service life. The fatigue failure of the airport pavement structure is not only related to the surface concrete but also affected by the structural condition index of the base, soil foundation, and pavement. If only the fatigue failure of concrete structure is considered, the service life of airport pavement may be overestimated. In distress control, in addition to treating the discontinuity area, the joint load transfer capacity should be evaluated and enhanced to improve the overall performance of the airport pavement.
