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...
متن کاملCoupled thermo-hydro-mechanical processes in fault zones during rapid slip
The physical processes which occur during an earthquake exhibit several coupled phenomena as large variations of stress, pore pressure and temperature take place in the slip zone. Thermo-poro-mechanical couplings due to shear heating can be associated to phase transition such as vaporization of the pore fluid, melting of fault gouge and to chemical effects such as dehydration of minerals or dec...
متن کاملCoupled thermo-hydro-mechanical model for porous materials under frost action: theory and implementation
This paper introduces the development and implementation of a multiphysical model to simulate the coupled hydro-thermo-mechanical processes in freezing unsaturated porous materials. The model couples the Fourier’s law for heat transfer, the generalized Richards’ equation for fluid transfer in unsaturated media, and the mechanical constitutive relationship. Coupling parameters were defined to tr...

متن کاملThermo- 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...
