| Summary: | While permafrost provides excellent bearing for structures, it may lose its strength to such an extent that it will not even support light structures when thawed. Differential settlement is normal and usually results in serious damage or building collapse. Pile foundations were used extensively at Inuvik, NWT, an area of continuous permafrost to depths of over 300 ft. The use of piles at Inuvik was a suitable foundation type for the majority of buildings and facilities. Même si le pergélisol fournit une excellente portance pour les constructions, il peut perdre de sa force ou de sa ré sistance à un point tel qu'une fois dégelé, il ne pourra mê me plus supporter des ouvrages légers. Le tassement diffé rentiel est normal et entraîne habituellement des dommages graves ou même l'effondrement des bâtiments. Les fondations sur pieux ont été employées abondamment à Inuvik (T.N-O) dans une zone de pergélisol continu jusqu'à des profondeurs dépassant 300 pi. L'emploi de pieux à Inuvik s'est révélé un choix de fondation approprié pour la majeure partie des bâtiments et des installations. Peer reviewed: No NRC publication: Yes |
