Influence of some EPB operation parameters on ground movements
(AEDIFICATIO PUBLISHERS, 2009)
Text en actes de congrés
Accés restringit per política de l'editorialSome of the details of EPB tunnelling are difficult to introduce in conventional numerical models, nevertheless there are some parameters that can be included in the analyses in a fairly easy way. The EPB operating ... -
Modeling of surface wear by the particle finite element method: application to tunneling processes
(2009)
Text en actes de congrés
Accés obertThis work introduces the advances in the Particle Finite Element Method (PFEM) for the modeling of contact and wear between solid materials. The PFEM is an original conjunction of solution strategies. The method has its ... -
Numerical solutions for tunnels excavated in strain-softening rock masses considering a combined support system
(2021-04)
Article
Accés obertIn this article, an alternative numerical procedure to calculate displacements and stresses of supported circular tunnels is proposed, considering the whole process of tunnel advancement, and sequential installation of the ... -
Rock bolt behaviour in stress-fractured ground: a FE analysis using zero-thickness interface elements and fracture-based constitutive laws
(2016)
Text en actes de congrés
Accés restringit per política de l'editorialA finite element analysis using zero-thickness interface elements of the Goodman type, which incorporate a fracture mechanics-based mixed-mode constitutive law, is presented to study stress-induced cracking and spalling ...
