摘　　要：以半刚性基层基底拉应变和路表弯沉为控制指标,利用弹性层状体系分析程序对某半刚性沥青路面典型结构进行了应力分析。根据Minner法则和不同的控制指标,计算分析了在目前交通组成情况下,沥青路面的使用年限和满足其正常使用时现有路面结构需要增加的路面厚度,对以轴载谱为依据的路面结构设计具有指导意义。In this paper, by using the analyzing program on elastic layer structure, the stress on a typical semirigid pavement structure is analyzed and the controlling standard is the strain on the bottom and the deflection on the surface of the pavement. With different kinds of fatigue equations and through the Minner method, the service life and required extending depth of the pavement based on the current traffic situation are gained. The presented results can be used in the design of the pavement's structure which is based on the axleload spectrum.
