    • Coupled analysis of double porosity swelling clays 

      Gens Solé, Antonio; Guimarães, Leonardo do N; Sánchez, Marcelo; Valleján, Beatriz (Springer, 2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The understanding of the coupled behaviour of highly active swelling clays is better achieved considering two structural levels and their interactions in the context of a double-porosity model. Hydraulic equilibrium between ...
    • Coupled hydro-mechanical and chemical analysis of fault reactivation during CO2 injection in carbonate reservoirs 

      Guimarães, Leonardo do N; Pereira, Leonardo C.; Gomes, Igor F.; Gens Solé, Antonio (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Injection of CO2 in saline aquifers or oil reservoirs cause changes of pressure, temperature, saturation and concentrations that affect the state of stress in the host rock, resulting in porosity and permeability variations. ...
    • Coupled THM analysis of a nuclear waste repository in crystalline rock 

      Sanchez, Marcelo Dolores; Dontha, L; Gens Solé, Antonio; Guimarães, Leonardo do N (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper presents the Thermo-Hydro-Mechanical (THM) analysis of an isolation system for high level nuclear waste. A geological disposal facility of such type encompasses both: natural (host rock) and engineered barriers ...
    • Coupled THMC analysis in porous media 

      Gens Solé, Antonio; Guimarães, Leonardo do N; Olivella Pastallé, Sebastià (IFSTTAR, 2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      A coupled thermo-hydro-mechanical-chemical (THMC) formulation is presented. The formulation combines a THM approach already existing and operational with the equations of reactive transport in a fully coupled manner. The ...
    • Coupled THMC modeling of unsaturated swelling clays: constitutive formulation and boundary value problems 

      Guimarães, Leonardo do N; Gens Solé, Antonio; Sánchez, Marcelo; Olivella Pastallé, Sebastià (Taylor & Francis, 2009)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      An appropriate understanding of the interaction and effects of thermal, hydraulic, mechanical and chemical (THMC) phenomena occurring in compacted swelling clay is greatly assisted by the development and use of coupled ...
    • Drying cracks in soils: current advances and challenges 

      Romero Morales, Enrique Edgar; Sanchez, Marcelo; Kim, Sewon; Guimarães, Leonardo do N; Zielinski, Marcin; Atique, Alvis; Manzoli, Osvaldo (2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper presents some current advances and challenges related to the behavior of soil subjected to drying and the consequent formation and propagation of cracks in the soil mass. Typical geotechnical problems associated ...
    • Factors controlling rock–clay buffer interaction in a radioactive waste repository 

      Gens Solé, Antonio; Guimarães, Leonardo do N; García Molina, Ángel; Alonso Pérez de Agreda, Eduardo (Elsevier, 2002)
      Article
      Accés obert
      The paper examines the interaction between host rock and a clay-based engineered barrier in the context of deep underground disposal of high-level radioactive waste. A large scale ‘‘in situ’’ heating test currently under ...
    • Formulation for the THMC analysis of clayey materials: application to radioactive waste disposal 

      Gens Solé, Antonio; Guimarães, Leonardo do N; Fernández, A.M.; Sánchez, M.; Olivella Pastallé, Sebastià (American Society of Civil Engineers (ASCE), 2008)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      A 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 used ...
    • HMC analysis of a tunnel in swelling rock 

      Berdugo de Moya, Iván Rafael; Guimarães, Leonardo do N; Gens Solé, Antonio; Alonso Pérez de Agreda, Eduardo (AEDIFICATIO PUBLISHERS, 2009)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The phenomenon of swelling in tunnels excavated through sulphate-bearing rock is quite frequent in some geological formations. The paper describes the case of the Lilla tunnel excavated in anhydritic-gypsiferous of Eocene ...
    • THMC analysis of saturation and heating processes of an expansive clay barrier in radioactive waste isolation 

      Guimarães, Leonardo do N; Gens Solé, Antonio; Sánchez, M.; Olivella Pastallé, Sebastià (CRC Press/Balkema, 2010)
