Theoretical and numerical analysis of the three-dimensional response of segmental tunnel linings subjected to localized loads

Segmental tunnel linings present a significant 3D response when they are subjected to localized loads or to other scenarios that produce different deformations of adjacent rings. The present paper analyzes the interaction mechanisms mobilized in such conditions, determining the most influence parame...

description Segmental tunnel linings present a significant 3D response when they are subjected to localized loads or to other scenarios that produce different deformations of adjacent rings. The present paper analyzes the interaction mechanisms mobilized in such conditions, determining the most influence parameters and their repercussion on the structural response of the lining. A complete set of numerical analyses is carried out on a complex 3D numerical model that accurately reproduces a real tunnel section on multiple scenarios. Numerical results show the structural benefits of the lining three-dimensional response when subjected to localized loads, allowing the determination of the influence presented by the main involved parameters. The surrounding ground stiffness determines the interaction degree achievable between adjacent rings, whilst lining longitudinal compression determines the maximum load for which a complete interaction is produced.
