.... The original foundation design included 4 inches (101.6 mm) of insulation which was not adequate to counteract thermal degradation below the building. A sandy gravel material with cobbles extended beneath the floor slab to depths ranging from 10 to 14 feet (3 to 4.3 m). This coarse granular layer was underlain...

... Abstract Global ice load criteria govern the stability of an Arctic offshore structure and its foundation. This paper reviews six case histories in which ice pressures have been measured, and the foundation response has been predicted and monitored. The global loads inferred from the two...

... ABSTRACT An actively refrigerated, slab on grade foundation was designed for a coal-fired electric generating facility with a total capacity of 11 megawatts. The facility was constructed to supply power to the Over-the-Horizon Backscatter site near Gakona, Alaska. The soil on which...

... ABSTRACT Subsurface and geocryological conditions impacting the construction of power structures in northeast USSR are reviewed. The sites are characterized by nonhomogeneous geological structure, cryogenic texture in the foundation rock or soil, and sharp differences in temperature conditions...

... ABSTRACT A case history and design review of the Kuparuk River Module Crossing and its refrigerated foundation are presented. The Kuparuk Crossing incorporated a number of design and construction innovations to meet the challenges of bridging a major Alaskan North Slope river. Among...

... ABSTRACT Thermosyphons have been used across Alaska and northern Canada as a means of stabilizing foundations built on permafrost. This paper describes a number of different applications including details of the installations. A brief discussion of the design methodology is also presented...

... ABSTRACT The ADOT Jim River Maintenance Building, located over permafrost in central Alaska, has experienced significant floor heave following startup in late 1986 of an active subgrade cooling system (SCS), even though foundation soils appear to remain frozen year round. After constructing...
