This paper provides a summary description of the selected results obtained in the
frame of the THERESA- project cosponsored by the European Commission (EC). The
numerical modeling of coupled thermal-hydraulic-mechanical (THM) processes with impact
on repository long-term safety was focused on simulation of a number of representative
laboratory experiments on rock salt samples. The scope of these calculations was the
validation of the actual capabilities of the constitutive model and to identify needs for further
improvements of the model. The measured development of volumetric strains and
permeability in the samples during loading process was compared posterior to calculation
results.
