| Abstract: | Taking a deep open excavation of Nanjing subway station as the engineering background,the deformation of the support structure of the excavation was studied using the common finite element software in two-dimensional. The analysis was compared with the spot inspections. The results shown that the two-dimensional finite element method was suitable for the strip subway excavation and could provide some references to the future deep excavation design. |
| Keywords: | deep excavation structure deformation two-dimension FEM subway station |
