    Conference report
    Restricted access - confidentiality agreement
    In this paper, a benchmark exercise from the DECOVALEX-2011 project is presented. Experimental results from a laboratory drying test in Opalinus Clay are used. First, the DECO- V ALEX project and the teams of the benchmark ...
  • Analysis of ground movements induced by diaphragm wall installation 

    Garitte, Benoit; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (CRC Press, 2010)
    Conference report
    Restricted access - publisher's policy
    The construction process of diaphragm walls can lead to movements in the surrounding area that are seldom taken into account. However, these movements may be important in situations where soft soils dominate. In this ...
  • Applications of multiphysical geomechanics in underground nuclear waste storage 

    Gens Solé, Antonio; Garitte, Benoit; Olivella Pastallé, Sebastià; Vaunat, Jean (Lavoisier Éditions, 2009)
    Article
    Open Access
    Deep 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 ...
  • Class A prediction of a mine-by test in an overconsolidated mudstone 

    Garitte, Benoit; Vaunat, Jean; Gens Solé, Antonio; Vietor, Tim (AEDIFICATIO PUBLISHERS, 2009)
    Conference report
    Restricted access - publisher's policy
    In this paper, 3D HM computations are performed to predict the rock response during the excavation of a new gallery (mine-by test) realized in Opalinus clay at the Mont- Terri laboratory, Switzerland. In a first part, ...
  • Comparative study of three in-situ heating test of anisotropic media: the HE-D, TER and ATLAS experiments 

    Garitte, Benoit; Sillen, X.; Li, XiangLing; Gilles, Armand; Vaunat, Jean; Gens Solé, Antonio (2009)
    Conference report
    Restricted access - publisher's policy
    The paper presents an interpretation ofthe Thermo-Hydro-Mechanical (THM) behaviour of three clays in three in-situ heating tests. First, the in-situ measurements are explored and common rock features are identified. Then ...
  • Coupled analysis of an in situ experiment in a soft argillaceous rock using a new constituive model 

    Vaunat, Jean; Garitte, Benoit; Gens Solé, Antonio (Taylor and Francis, 2006)
    Conference report
    Restricted access - publisher's policy
    The paper addresses the issue of the description of the coupled thermo-hydro-mechanical behaviour of argillaceous rocks. A constitutive law, developed for this type of materials, is firstly described. It is based on an ...
