| Abstract: | 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. |
