摘　　要：为了合理设计军用机场沥青混凝土道面,以设计飞机作为计算荷载,按照疲劳等效原理,分析了不同飞机之间的交通量换算关系,根据军用机场道面使用特点、组成结构材料特性和损坏现象,采用面层、基层、底基层底部的拉应力和面层的剪应力作为结构设计指标,应用弹性层状体系理论设计了军用机场沥青混凝土道面。在H-6、MD-82和B727-100组成的混合交通中,分别用H-6和MD-82作为设计飞机,采用道面结构设计程序Pave2000进行结构层厚度计算。计算结果表明,以H-6为设计飞机,下基层设计厚度为34 cm,以MD-82为设计飞机,下基层设计厚度为33 cm,两者相对误差仅为3.03%,说明此设计方法是正确的。In order to reasonably design the asphalt concrete pavement of military airfield, design airplane was regarded as calculating load, the conversion relations of traffic volumes between different airplanes were analyzed by using fatigue equivalent principle, the tensile stresses of surface, base, subbase and the shear stress of surface were regarded as the structure design indices, according to the characteristics of pavement load, pavement material and pavement damage, airfield pavement was designed by using elastic layered theory. When the mix traffic consisted of H-6, MD-82 and B727-100, H-6 and MD-82 were used as the design load to design asphalt pavement separately, and the structure thicknesses of pavement were computed by using the program of Pave2000. Computation result shows that the design thickness of subbase is 34 cm with H-6, it is 33 cm with MD-82, their relative error is only 3.03%, which indicates that the design method is correct. 8 tabs, 2 figs, 16 refs.
