ABSTRACT: An experimental research site has been constructed in the Northwest Territories to examine the efficacy of long, narrow, hollow pipes inserted into the ground as a cooling mechanism to stabilize permafrost. The pipes were installed in four different ways in order to achieve a broader picture of the mechanisms at work. The resulting ground temperatures over the winter months are presented. Promising results have been obtained.

RÉSUMÉ: Un site de recherche expérimental a été construit dans les Territoires du Nord-creux, longs et étroits insérés dans le sol comme mécanisme de refroidissement pour stabiliser le pergélisol. Les tuyaux ont été installés de quatre façons différentes afin de déterminer leur mécanisme de fonctionnement. Les résultats du suivi des températures du soété obtenus.
