摘　　要：为了探究环氧沥青混凝土加铺层这种机场道面修建技术,分析复合道面结构参数对荷载应力的影响,利用ANSYS建立了机场复合道面三维有限元模型,计算荷载为SU-27飞机荷载,选取了环氧沥青加铺层顶面荷载应力、底面对应接缝处应力、底面对应接缝处弯沉值以及旧道面板最大拉应力为考察指标,分别计算了各结构参数对荷载应力的影响,并利用正交设计分析了各结构参数对荷载应力影响的显著性。结果表明:加铺层厚度、加铺层模量、基础模量与考察指标都显著相关,应作为机场环氧沥青加铺层设计的主要分析指标,因此,在设计环氧沥青加铺层时要选取合理的加铺厚度,并对基础进行必要的检测,采取相应的技术措施进行处理。In order to explore airport pavement maintenance technology of epoxy asphalt concrete overlay,analyze the load stress of composite pavement structure,using the ANSYS finite element program establish model.Taking SU-27 as the computational load,the load stress of pavement overlay,the stress of seam crossing,the pavement overlay′s surface deformation and the tensile stress of old concrete pavement were calculated as analytic index,and the significance of pavement structural parameters to the load stress was analyzed by the orthogonal design method.The result showed that the add layer depth,add layer modulus,modulus of the foundation are significant correlation to the tensile stress of pavement overlay,they should be the key index of load stress of double-layer airport pavement.Therefore,reasonable layer depth should be selected when designing epoxy asphalt concrete overlay,and the foundation should be make necessary testing and corresponding technology processing.
