The mechanical response analysis of the airport asphalt pavement considering horizontal load
In order to research the mechanical response of asphalt pavement under horizontal load which produced by the large aircraft braking process,large-scale finite element software is used in this paper.The model of main landing gear load is established to analyze the change of principal mechanics indexes of airfield pavement when the aircraft has different landing distance.The results show that:the horizontal load has a significant influence on the normal stress of landing direction,but the influence area is concentrated in the rear of the wheel.The horizontal load has more effect on horizontal shear stress and longitudinal shear stress,while has less effect on tensile stress of surface layer bottom,tensile tress of base course bottom and transverse shear stress.The tensile stress of surface layer will increase significantly when the braking distance is less than 2000m.Meanwhile,thickening surface layer could decrease the tensile stress and increase the fatigue lifetime apparently.
