THMC coupling in partially saturated geomaterials
A theoretical formulation for the performance of coupled thermo-hydro-mechanical and chemical analysis (THMC) of problems involving partially saturated geomaterials is presented. Both homogeneous and heterogeneous chemical reactions are considered. The incorporation of chemical equilibrium is achieved by the direct minimization of Gibbs free energy. Although the formulation is general, particular consideration has been given to the phenomena that are likely to occur in compacted swelling clays used in isolation barriers. An example of application is described involving the coupled THMC analysis of a large scale in situ heating test of an engineered barrier.
