摘　　要：采用大型通用有限元软件ANSYS,对干线公路改建刚性基层沥青路面结构进行力学响应分析,探讨旧路强度不均匀对刚性基层路面结构内部应力的影响,针对目前旧路改建刚性基层沥青路面结构存在的不足,提出应对措施。By adopting the large scaled finite element software ANSYS,the mechanical response analysis of the Trunk Highway Reconstruction rigid base asphalt pavement structure was carried out,the influence of the non-uniform strength of the old road on the internal stress of the rigid pavement structure is discussed,in view of the existing shortcomings of rigid base asphalt pavement structure,and puts forward some advice.

关 键 词：不均匀地基 旧路改建 刚性基层 数值分析
