In the context of a large scale in-situ PRACLAY Heater test which is currently running at the HADES underground research facility (URF) in Mol, Belgium, an analytical solution is developed to study the Thermo-Hydro-Mechanical (THM) responses in the Boom Clay, backfilling sand and supporting liner around the heated PRACLAY gallery. After sufficient verification, the present solution is applied in the PRACLAY Heater test for a predictive reference calculation and a parametric sensitivity study. The new analytical solution proves to be a convenient tool for a good understanding of the resulting coupledTHM behaviour and is therefore valuable for the interpretation of measured data in engineering practices and for a rational design of potential radioactive waste repositories.
