摘要:
针对飞机在飞行区不同区域行驶状态的极大差异造成的沥青加铺结构局部区域早期变形破坏。本文基于ABAQUS软件平台分析了大型飞机荷载、温度及行驶速度变化下加铺结构的剪应力、剪应变及永久变形规律，表明在重载、高温、低速三者耦合作用下沥青加铺层受力及变形将处于极限不利状态。而通过合理安排材料类型组合及厚度可以明显降低平行滑行道、联络道的早期轮辙病害，改善道面服务水平。因此，在现有设计方法的基础上，提出以容许剪应力及容许轮辙为验算指标的飞行区不同区域沥青加铺结构差异设计方法。
Abstract:
According to the early partial deformation failure, which was caused by great difference of the traveling state in different flighting areas, based on ABAQUS softwareplatrorm, this paper analyzed the change law of shear stress、shear strain and permanent  deformation when aircraft load, temperature and driving speed were changed. It showed that the force and deformation of asphalt overlay would be in the limit under the coupling effect of three kinds of heavy load, high temperature and low speed. By reasonable design of material type combination and thickness, the early rutting of parallel taxiway and liaison road could be significantly reduced, and the service level of pavement could be improved. Thus, based on the existing design, this paper presented a design method for different regions of asphalt overlay in airport pavement, that the allowable shear strss and allowable rut for checking index.
