Thermo-Elasto-Plastic Consolidation Analysis with Water Phase Change
The aim of this paper is numerical analysis of the thermal consolidation processes in the framework of the coupled hydro-thermo-mechanical (HTM) modeling of soils due to mechanical and thermal loads. A fully coupled finite element model for non-isothermal elasto-plastic multiphase materials based on Porous Media Mechanics is therefore developed. In particular, the ACMEG-TS thermo-elasto-plastic constitutive model for variably saturated clayey soils has been implemented in the finite element code COMES-GEO for the analysis of non-isothermal deformable multiphase porous materials. The non-isothermal consolidation of a Boom clay column is studied in order to analyse the coupled effects of mechanical and thermal loads on this material, which is a candidate for an underground nuclear waste storage facility. A preliminary result of a heating case where the temperature is above the boiling value and liquid water phase change develops is also shown.
