Guide to a Field Description of Permafrost for Engineering Purposes

Almost one half of Canada's total land surface is underlain by permafrost and its existence has manyimplications to both scientific and engineering interests. Engineering experience has indicated thatsite investigations are essential in permafrost areas but no standard method for reporting permafrostconditions has been used or is available. This booklet has been prepared with the hope that the descriptivesystem outlined will fulfil this need.Au Canada, le sous-sol de presque la moiti\ue9 de la terre \ue9merg\ue9e est constitu\ue9 par le perg\ue9lisol, et sa pr\ue9sence a de nombreuses r\ue9percussions sur des centres d'int\ue9r\ueat tant scientifiques que techniques. Les ant\ue9c\ue9dents en mati\ue8re d'ing\ue9nierie r\ue9v\ue8lent que la reconnaissance des sols est essentielle dans les r\ue9gions o\uf9 l'on trouve du perg\ue9lisol; cependant, aucune m\ue9thode uniforme de signalisation des conditions de perg\ue9lisol n'a \ue9t\ue9 jusqu'ici utilis\ue9e, ni est m\ueame disponible \ue0 ce jour. On a pr\ue9par\ue9 ce livret en esp\ue9rant que le syst\ue8me descriptif qui y est d\ue9crit r\ue9pondra \ue0 ce besoin.Peer reviewed: NoNRC publication: Ye
