摘　　要：采用Fortran语言编制无砟—有砟轨道过渡段的力学分析程序。对比分析无砟—有砟轨道过渡段刚度过渡设置方式,并提出几种过渡段的结构设计方案,对无砟—有砟轨道过渡段的设计施工有一定的指导意义。It had established ballastless-ballast track transition sections＇ mechanics analysis program with FORTRAN Language. It was analysed and contrased the dynamic behavior of several kinds of stiffness setting. Several structural design of the transition remedies was listed.The article on the ballastless-ballast track transition sections design and construction had a certain significance.

关 键 词：无砟轨道 有砟轨道 过渡段 刚度差
