Thermo-hydro-mechanical Coupling in Clay Barriers

A complete thermo-hydro-mechanical model is presented to tackle the complex coupling problems encountered in clay barriers. A detailed formulation coupling the heat, moisture (liquid water and water vapour) and, air transfer in a deformable unsaturated soil is given. The formulation of the AlonsoGens’s mechanical model for unsaturated soil is also incorporated. The sensitivity to some parameter...

Thermo- and hydro-mechanical processes along faults during rapid slip

Field observations of maturely slipped faults show a generally broad zone of damage by cracking and granulation. Nevertheless, large shear deformation, and therefore heat generation, in individual earthquakes takes place with extreme localization to a zone <1–5 mm wide within a finely granulated fault core. Relevant fault weakening processes during large crustal events are therefore likely to b...

Preliminary laboratory thermo - hydro - mechanical characterization of Opalinus clay

1 INSTRODUCTION In the concept of geological radioactive waste disposal, argillite is being considered as a possible host rock in various countries such as France and Switzerland. This material is chosen thanks to its extremely low permeability that is required to limit the transfer of radioactive elements from the waste package towards the environment. During the construction and exploitation ...
