摘　　要：利用Bisar及ANASYS建立新型环氧沥青混凝土道面(SEA)结构模型,通过分析A380-800飞机主起落架构造及多项荷载参数,对飞机荷载作用下SEA机场道面面层应力、应变及弯沉等结构响应进行分析,并拟合Bisar三阶差值三维弯沉图。结果表明,A380飞机荷载作用在SEA道面上时,A380飞机主起落架前六轮主要承受载荷,应力应变分布较为均匀,出现双峰值现象;后四轮纵向应力应变较横向大,易出现应力集中现象。大型飞机荷载作用于SEA环氧沥青混凝土道面弯沉值较小,相比普通SAA沥青道面,SEA沥青混凝土道面具有较好的路面力学效应。By utilizing the new epoxy asphalt concrete pavement (SEA)structure model with the soft Bisar and ANSYS,the main gear configuration and multiple load parameters are analyzed.In the analysis, the influence of the stress and strain and the deflection on surface course pavement are not only calculated, but also the inflection three-dimensional interpolation picture fitted by Bisar.When the A380 aircraft is acting on the SEA pavement,the results show that the six wheels in front of main landing gear bear load mainly and the stress and strain distribute uniformity with double peak phenomena.But for the four wheels in rear,the stress and strain on the direction of Y are more than X with concentration phenomena. In addition,a large aircraft like A380 aircraft acting on the epoxy asphalt concrete pavement(SEA)has lesser deflection,having better mechanical effect compared with the normal asphalt concrete pavement (SAA).
