Summary: | Available literature on the problem of establishing reliable, permanent bench marks in permafrost areas is reviewed. The factors that influence stability are noted and some of the methods devised to provide reliable bench marks are described. Finally, the design, installation and performance of a bench mark used in the north of Canada by the Division of Building Research is described in detail. L'auteur passe en revue les documents qui traitent des problèmes concernant l'établissement de repères permanents dans les zones de pergélisol. Il mentionne également les facteurs qui influent sur la stabilité, et décrit certaines des méthodes concues pour obtenir des repères fiables. Enfin, il expose en détail la conception, l'installation et l'efficacité d'un type de repère utilisé dans le nord du Canada par la Division des recherches en bâtiment.
