| Abstract: | The Goodman element is used to simulate the interaction between soil and structure. Taking the deep foundation pit of Huangpu river walking tunnel as an example, the influence of stiffness of Goodman element on displacement of wall and surface settlement is analyzed with finite element method. This provides a basis for the choice of stiffness coefficients on numerical calculation of soft soil foundation pit and informationalized construction. |

| Keywords: | contact element stiffness coefficient deep foundation pit deformation |
