Abstract

In response to the trend of developing aircraft with heavier loads and higher tire pressures, a full-scale nine-block pavement panel three-dimensional finite element analysis model was established using ANSYS software to study the stress and deformation of cement concrete pavement under different loads applied at different positions. The results showed that the thickness of the pavement panel significantly affected the stress at the bottom of the panel. By considering the reliability, the ultimate limit state of the pavement was analyzed, and it was found that for aircraft with a tire pressure greater than 1.6 MPa, the use of the aircraft type should be strictly controlled when the pavement thickness is 24 cm. Finally, the ACNPCN method was used to study the overloading situation of the pavement, and the requirements for overloading use were established. By consulting the chart, the airport management department can intuitively understand the requirements for pavement thickness for different aircraft tire pressures and the range of tire pressure that the pavement thickness can accommodate, making it easier to control the overloading use of aircraft at the airport.
