The results a numerical simulation of an in situ test, performed in the HADES underground laboratory (Mol, Belgium), are presented. The experiment (known as BACCHUS 2) demonstrates an installation procedure for a clay based backfill material made of a mixture of high density Boom clay pellets and Boom clay powder. The results achieved have been used as one of a series of validation exercises designed to assess the performance of a thermo-hydro-mechanical computer code.
