Deformation Analysis of Shield Tunnel
This paper is concerned with the finite element analysis of shield tunnel for the deformation and internal forces in the surrounding soil and in the tunnel lining. Curved Mindilin beam element is recommended to model the tunnel lining in order to ensure deformation compatibility between the lining element and the soil element. Numerical methods are presented to simulate the staged construction and to consider the influence of ground lost during the tunnel construction. Finally, a practical problem is analyzed to show the performance of the proposed numerical procedures.
