摘要: In the context of a feasibility study for geological disposal nuclear waste, an in situ heating experiment was performed order to thermo-hydro-mechanical responses barrier variation temperature. The carried out at Mont Terri underground research laboratory Switzerland. This paper presents numerical modelling experiment. An elasto-plastic damage model has been used describe mechanical behaviour formation (a mudstone). constitutive is extended description thermo-poro-mechanical saturated porous media. A finite element method with fully coupled algorithm employed solution boundary value problems. Variations temperature, pore pressure and deformation during phases have evaluated compared measurements. allows interpretation phenomena observed
