摘　　要：以弹性半空间体为计算理论基础,对半刚性基层沥青路面结构的力学响应进行了分析,描述了BISAR软件对半刚性基层沥青路面结构设计指标的计算过程,并利用可靠度方法验证了各设计指标的合理性。在路面结构设计指标合理的基础上,分析了不同车辆轮载对路表弯沉值、基底拉应力和路表剪应力的影响规律。Based on the elastic half-space theory,the mechanical response of semi-rigid base asphalt pavement structure is analyzed in this paper.The calculation process of structural design index by BISAR software is described in detail and the rationality of each design index is verified by the reliability method.On the base of reasonable pavement structure design index,the influence law of different vehicle loads on the bending and sinking value,the tensile stress of the base and the shear stress of the pavement surface are analyzed.
