Three-Dimensional Numerical Modelling of Shield Tunnel Lining

摘要

The most important problem for the design of the shield tunnel linings is whether the design modelrncan reflect the actual stress of the linings. Various methods for the design of segmental tunnel liningsrnare discussed and a new three-dimensional shell-spring design model is put forward. The shell-springrnand beam-spring model were used to analysis the sequence and staggered lining arrangement, fromrnwhich useful guidance for designing the segmental linings can be drawn.
