Abstract
The most important problem for the design of the shield tunnel linings is whether the design model can reflect the actual stress of the linings. Various methods for the design of segmental tunnel linings are discussed and a new three-dimensional shell-spring design model is put forward. The shell-spring and beam-spring model were used to analysis the sequence and staggered lining arrangement, from which useful guidance for designing the segmental linings can be drawn. (A) This paper was presented at Safety in the underground space - Proceedings of the ITA-AITES 2006 World Tunnel Congress and the 32nd ITA General Assembly, Seoul, Korea, 22-27 April 2006.
