Research ArticleOpen accessIn the keywordsAnalysis of the Interaction between the Lining of a TBM Tunnel and the Ground Using the Convergence-Confinement MethodPierpaolo OresteThe support used when a tunnel is excavated by a shielded TBM is complex because it consists of two different materials: A concrete segmental lining and a filler annulus between the lining and the tunnel wall. A detailed analysis of the behavior of such a support system requires a three-dimensional numerical modeling and should also consider the presence of the … …American Journal of Applied Sciences, Vol. 12, Issue 4 · 17 Jun 2015 · 7,183 accessesView PDF Cite

Research ArticleOpen accessIn the keywords3D Modelling for Mechanized Tunnelling in Soft Ground-Influence of the Constitutive ModelNgoc-Anh Do, Daniel Dias, Pierpaolo Oreste, Irini Djeran-MaigreThe main purpose of this study was to provide a three-dimensional numerical model which would allow to show the influence of the constitutive model of the ground on the tunnel lining behaviour and displacement field surrounding the tunnel. Most of the processes that occur during mechanized excavation have been simulated in this model. Besides the well-known elastic linear perfectly plastic … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 8,371 accessesView PDF Cite
