摘　　要：以白云山车站隧道为依托,采用有限差分数值分析软件,对连拱与大跨度车站隧道过渡段进行了施工力学行为研究,获得了过渡段施工过程中隧道周边位移、塑性区和应力场的分布规律。The mechanical performance of the changeover portion of a Large-span Railway Station Tunnel is studied by finite difference numerical analysis software, based on the construction of baiyun- shan railway station tunnel. The displacement, plasticity area and stress distribution of the changeover portion in the construction process are obtained.

关 键 词：车站隧道过渡段 力学行为 数值模拟
