In this paper numerical predictions of settlements induced by tunnelling in fine-grained soils are presented. The numerical analyses are aimed at separately establishing the relevance of stress-induced anisotropy and that of the structure degradation processes by adopting a constitutive model recently implemented in the finite element code Plaxis. The analysis of the results indicates that no significant influence of the considered aspects is relevant for tunnel induced ground settlements for volume losses which are typical of EPB or slurry shield tunnelling.

Abstract
In this paper numerical predictions of settlements induced by tunnelling in fine-grained soils are presented. The numerical analyses are aimed at separately establishing the relevance of stress-induced anisotropy and that of the structure degradation processes by adopting a constitutive model recently implemented in the finite element code Plaxis. The analysis of the results indicates that no significant influence of the considered aspects is relevant for tunnel induced ground settlements for volume losses which are typical of EPB or slurry shield tunnelling.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
