Abstract

The design model of shield segment was discussed,and a new shell-spring design model was put forward.The establishing process of model was also discussed in detail,and shell-spring model and beam-spring models were used to analyze the tunnel with sequential and staggered segment seams.The calculated results with these two models were compared.
- shield segment,
- shell-spring model,
- beam-spring model,
- joint stiffness
