ABSTRACT: An experimental research site was constructed in Northern Canada to examine the ability of long, narrow, steel pipes to act as heat drains to cool ground temperatures in an effort to stabilize permafrost. The test site was built in a vacant gravel lot in Yellowknife, in an area that has had issues with permafrost degradation. Narrow steel pipes were used since they can be rapidly installed using a compressed air launcher, making the heat drains a feasible option for long highway corridors. The results show a general ground cooling trend in the presence of heat drains.

RÉSUMÉ: étroits, en acier, de conduire la chaleur (drains de refroidissement) afin de refroidir le sol dans le but de stabiliser le pergélisol. Le site a été construit dans un terrain vacant de gravier à Yellowknife, dans une région qui a eu des problèmes avec la dégradation du pergélisol. Des tubes étroits en acier ont été utilisés car ils peuvent être installés corridors routiers longs. Les résultats montrent une tendance générale de refroidissement du sol en présence des drains de refroidissement.
