A fully coupled elastic–plastic hydromechanical model for compacted soils accounting for clay activity
(2012-01-11)
Article
Accés restringit per política de l'editorialA constitutive model, accounting for multiphase and multiscale coupling, is proposed for the water retention domain and the stress–strain response of compacted clayey soils. The model is based on a conceptual interpretation ... -
Applications of multiphysical geomechanics in underground nuclear waste storage
(Lavoisier Éditions, 2009)
Article
Accés obertDeep geological disposal in suitable host rocks is the favoured strategy for the storage and disposal of heat-emitting high level nuclear waste. A rational design of repositories requires a good understanding of the ... -
Effect of thermo-coupled processes on the behaviour of a clay barrier submitted to heating and hydration
(2010)
Article
Accés obertThe storage of high level radioactive waste is still an unresolved problem of the nuclear industry, being geological disposal the most favoured option and, naturally, the one requiring the strongest geo-mechanical input. ... -
Étude du comportement des limons loessiques soumis aux vibrations ferroviaires
(Universitat Politècnica de Catalunya, 2003-09-30)
Tesina
Accés obertÀ partir des enregistrements de paramètres de forage sur le tracé TGV Nord, on a montré la présence des limons décomprimés caractérisés soit par la forte porosité soit par la présence de fontis. Ces limons, non saturés ... -
Hydro-mechanical coupling in zero-thickness interface elements, formulation and applications in geomechanics
(CRC Press, 2014)
Text en actes de congrés
Accés obertZero-thickness joint/interface elements of the Goodman type, have been advantageously used to solve many problems in solid mechanics involving material interfaces or discontinuities. Some years ago, the authors have also ... -
Mechanics of unsaturated geomaterials applied to nuclear waste storage
(ISTE/WILEY, 2010)
Capítol de llibre
Accés restringit per política de l'editorial -
Numerical stress initialization in geomechanics via the FEM and a two-step procedure
(CIMNE, 2015)
Comunicació de congrés
Accés obertThe knowledge of the in-situ stress field in rock masses is crucial in different areas of geo-engineering, such as mining or civil underground excavations, hydrocarbon extraction, CO2 storage, hydraulic fracture operations, ... -
Stability of anchored sheet wall in cohesive-frictional soils by FE limit analysis
(2013-06-03)
Article
Accés obert -
Study on multi-period palaeotectonic stress fields simulation and fractures distribution prediction in Lannigou gold mine, Guizhou
(Springer Nature, 2023-12)
Article
Accés obertA significant controlling factor for gold mineralisation is the tectonic stress field, and the fractures formed under its action are the migration channels and ore-holding spaces of ore-forming fluids, which often directly ... -
THMC analysis of saturation and heating processes of an expansive clay barrier in radioactive waste isolation
(CRC Press/Balkema, 2010)
Text en actes de congrés
Accés restringit per política de l'editorialA fully coupled formulation combining reactive transport and an existing thermo- hydro-mechanical (THM) code is briefly described. Special attention has been given to phenomena likely to be encountered in clay barriers ...
