Objective The in situ tests carried out in the Varangeville mine (France) are described. This is part of a larger research programme on the mechanical behaviour of a salt massif. The aim of the in situ tests was to collect data for the validation of the behaviour law, based on the laboratory tests. Those tests consisted on the one hand of the short term mechanical characteristics measurement and on the other hand of the long term creep measurement of borehole walls. The second part required the construction of a prototype designed to measure the creep of borehold walls while applying a constant internal pressure set to a chosen value. The tests were carried out in a pillar of the mine. At first examination, the results seem to be inconsistent with the results of the modelling. It must be concluded that the mechanical characteristics of the massif near the borehole are modified as a result of the drilling; this appears probable from the fissure relaxation observed in the cores.
