| Summary: | This state of the art review summarizes key points of present knowledge in North America and major problem areas relative to engineering design and construction in permafrost regions. Topics discussed include the special importance of proper site selection and investigation, environmental engineering and protection constraints, current concepts of foundation design including footings, piles, ground anchors, foundations near or in water bodies and control of frost heave, design criteria for roads, railroads and airfields, North American experience with dams and reservoirs, excavation and underground construction studies in frozen ground, drainage, groundwater movement and artesian water conditions and problems, difficulties of providing reliable water, waste disposal and other utilities systems at reasonable cost in permafrost regions and the state of the art in the field of petroleum production and pipelines. Areas in which further research and development are required for improvement of engineering design and construction are summarized in a concluding section of the paper. Le présent exposé de synthèse résume les points saillants des connaissances actuelles en Amérique du Nord et les principaux problèmes que suscitent les études techniques et la construction dans les régions de pergélisol. Les sujets traités comprennent l'importance particulière d'une étude et d'un choix appropriés de l'emplacement, les exigences de l' aménagement et de la protection de l'environnement, la conception actuelle des fondations, y compris les semelles, les pieux, les ancrages au sol, les fondations dans les nappes d'eau ou près de celles-ci et la prévention du soulè vement dû au gel, les critères de calcul des routes, des lignes de chemin de fer et des terrains d'aviation, l'expé rience des barrages et des réservoirs acquise en Amérique du Nord, les études d'excavation et de construction souterraine dans un sol gelé, le drainage, le mouvement des eaux souterraines et l'état et les problèmes des eaux arté siennes, les difficultés ... |
