Displacement Field Study on the Full Width of Rigid Airport Pavement to Aircraft Loadings

Abstract

Considering the joint loading-transfer effect, a 3-D finite element model which consists of thirty full-scale slabs is established. Making the aircraft loads act on different positions and calculating their vertical displacements. The results indicate that the loading area is compressive and the regions far away from loading area are tensile and that the vertical displacement curves change dramatically when aircraft wheels act on different locations.

Technical Evaluation of a Runway Using the Deflection Method

“…According to the ICAO (International … 1983), previous observations have shown a strong general correlation between deflection of a pavement under wheel load and repetitive landing applications of that wheel load resulting in severe deterioration and failure of the pavement. X. M. Zhang and Q. Dong (2012) calculated vertical displacements caused by loading, and they found that the loading area of the pavement was compressive, but regions of the pavement far away from the loading area were tensile. Loading data of a Boeing 737-800 aircraft were used as an example for the calculation.…”

“…M. Zhang and Q. Dong (2012) discovered that significant influences of vertical displacements of loads caused by landing gear occur within 15 metres of the aircraft taxiing direction and 45 metres of entire width of the runway pavement. The touchdown zone of the runway pavement is the area with the highest stresses Downloaded by [UNAM Ciudad Universitaria] at 11:07 22 December 2014Aviation, 2013 …”
