Research Institute of Geotechnical Engineering, Hohai University, Nanjing 210098, China; 2. College of Environmental Science and Technology, Hohai University, Nanjing 210098, China 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. Key words: shield segment; shell-spring model; beam-spring model; joint stiffness 1.2 m [6] 20% 4 [1] [2-5] ITA
