| Abstract: | In this paper,for the tunnel in Guangzhou Metro Line 2 under the Guangzhou Railway Station,the influence of shield construction on the deformation of the tunnel surrounding rocks and the ground subgrade is analyzed using the elasto-plastic finite element method.The deformation values of the tunnel surrounding rocks and the ground subgrade caused by the different geostatic release during shield construction are compared.It provides a reference for the design and construction. |

| Keywords: | shield construction geostatic stress surrounding rock subgrade deformation |
