| Abstract: | The ground settlements and the disturbance of soil around tunnel by shield driven are summarized by means of measurement of Tianjin No.1 subway line project. According to the actual engineering, a 3D FEM model is proposed to simulate the excavating of shield tunnel by means of general FEM program ABAQUS; the model change method is put forward to imitate moving-forward shield process. And the results of simulation are compared with the results of measurement. |
