Abstract

The aim of this paper is to study the effect of the interaction between rings produced due to the axial load (and owing to the nature of the constructive process) on the structural behaviour of segmented tunnels. This analysis was performed by using a non-linear analysis with the Finite Element Method (FEM). Considering non-linear behaviour of the material, the segments were modelled by using 3D solid elements. Segment joints and ring joints were modelled by using contact elements. The results indicate that the axial load resulting from the interaction between the rings changes the structural behaviour of the lining in that its structural capacity is increased.
