Thermo-hydro-mechanical Coupling in Clay Barriers
نویسندگان
چکیده
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 parameters and their determinations are analysed. Finally, a small scale wetting – heating test on compacted bentonite is performed for validation; the numerical results are compared to the experimental measurements.

Effect of thermo-coupled processes on the behaviour of a clay barrier submitted to heating and hydration.
The 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. Most conceptual designs for the deep geological disposal of nuclear waste envisage placing the canisters containing the waste in horizontal drifts or vertical boreholes. The em...
متن کاملPreliminary 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 ...
متن کاملThermo-plasticity of Soils at Various Saturation States: a Constitutive Model
This paper presents a highly-coupled thermo-plasticity model for unsaturated soils. The effect of temperature on the mechanics of unsaturated soils is briefly addressed. Then the equations of the developed model, so-called ACMEG-TS, are detailed. Finally, the model is validated by the means of comparisons with experiments. This constitutive model constitutes an effective tool for modelling the ...
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-mechanical high-cycle fatigue analysis of exhaust manifold of turbocharged engine with two-way coupling FSI
NNowadays, car manufactures in order to increasing torque and power with consider to fuel consumption, have swept to production of turbocharged engines. With consider to exhaust gas-temperature rises in boosted engines, recognition of critical locations of exhaust manifold in the worse condition of engine (full load and maximum speed), to prevent fracture of exhaust manifold is very important. ...
