Structural analysis of DEW line station DYE-2, Greenland : 1983-1988 by Michael R Walsh( Book )

3 editions published in 1998 in English and held by 24 WorldCat member libraries worldwide

DYE-2, a Distant Early Warning station, is located on the Greenland ice cap approximately along the Arctic Circle, 470 km from the west coast. The viscous nature of the material on which the structure is grounded made periodic monitoring and maintenance of the supporting structure necessary This report analyzes the stresses developed within the structure from the last major maintenance operation, a 64-m sideways move in 1982 to a new foundation, to the final set of stress measurements taken at the abandoned site in 1988. Conclusions drawn from these measurements and the subsequent analysis were that the building system was continuing to tilt in one direction because of differential footing settlement caused by changing footing conditions, and high structural stresses would make it unsafe for reoccupation after December of 1988 unless emergency maintenance was performed. The U.S. Air Force officially abandoned the site in August 1988 as a result of this analysis

Measurement of forces within the structural frame of DEW line ice cap stations DYE-2 and DYE-3 by Wayne Tobiasson( Book )

3 editions published between 1972 and 1974 in English and held by 17 WorldCat member libraries worldwide

Regional straining of the ice cap and differential settlement and tilt of footings has induced secondary loads into the structural frame of these facilities. These loads have been measured using hydraulic cylinders at sway bolt interaction points. The measurements indicate that large secondary loads exist within these facilities. It is recommended that structural components be analysed in detail to assess the influence of the measured loads on the integrity of each structure. (Author)

An investigation of the snow adjacent to DYE-2, Greenland by Herbert T Ueda( Book )

3 editions published in 1981 in English and held by 10 WorldCat member libraries worldwide

Snow samples from five 50-ft (15.2-m) deep holes, augered adjacent to the west side of DEW Line Station Dye-2 in Greenland, were investigated for density and unconfined compressive strength. Forty-two percent of the recovered cores were tested. Ninety-three percent of the samples tested had a length/diameter ratio greater than 2:1. The loading rate was 2 in./min (51 mm/min). Sample end-effects appeared to influence a high percentage of the failures. The heavily disturbed nature of the materials is evidenced in the widely scattered values of density and strength with depth. A minimum and maximum strength value of 31 psi (0.21 MPa) and 1065 psi (7.34 MPa) respectively were obtained from a hole located 50 ft (15.2 m) from the structure. Using an approach similar to that used prior to the DYE-3 move in 1976, a safety factor exceeding 6.5 is obtained against a brittle bearing failure based on a maximum footing design load of 2000 lb/sq ft (96 kPa).

Drilling through the Greenland ice sheet by Herbert T Ueda( Book )

1 edition published in 1968 in English and held by 7 WorldCat member libraries worldwide

In July 1966 a USA CRREL drilling team succeeded in penetrating the Greenland ice sheet at Camp Century, drilling through 4550 feet of ice and 12 feet of sub-ice material. The objectives of the project were to gain an understanding of the basic flow mechanism of large ice masses and to collect continuous, undisturbed cores for scientific analysis. The two techniques of core drilling used to complete the hole were thermal drilling and electrodrilling. This preliminary report describes the drilling equipment and techniques used at Camp Century from 1963 to the completion of the deep drill hole in 1966

Fifty years of Soviet and Russian drilling activity in polar and non-polar ice : a chronological history by Herbert T Ueda( Book )

4 editions published in 2007 in English and held by 6 WorldCat member libraries worldwide

Soviet and Russian drilling activity in ice began in 1955 while conducting temperature surveys on a glacier in Franz-Josef Land in the Arctic and continued to 1960 on the glaciers of the polar Ural and the northern Tien Shen mountain ranges. In 1956 the first Complex Antarctic Expedition (CAE) was formed and the first Antarctic drilling was conducted in October of 1956 near Mirny Station. Later, the expeditions were referred to as Soviet Antarctic Expeditions (SAE) and Russian Antarctic Expeditions (RAE). Early efforts were conducted with hand drilling equipment followed by mechanical rotary and percussion drilling techniques. Thermal (flame and thermal electric) boring drills and later thermal coring drills eventually culminated in drills of the TELGA type for thermal drilling deep, dry holes. One such hole reached a depth of over 900 m at Vostok. Use of TBZS type thermal drills for drilling in fluid-filled holes were also developed, as was a technique using anti-freeze to dissolve the melt water formed, the dilute solution then remaining in the hole to provide the necessary hydrostatic balance. An electro-mechanical drill KEMS was first introduced on Vavilov Glacier, Severnaya Zemlya (Russian Arctic) in 1984 and then in 1989 at Vostok Station. Five major holes have been drilled at Vostok, the last one stopped in 2006 (RAE 51) at a depth of 3650 m, 100 m above Lake Vostok. This report chronologically summarizes the Soviet and Russian efforts over the last 50 years
Flexural Strength of Ice on Temperate Lakes: Comparative Tests of Large Cantilever and Simply Supported Beams by A. J Gow( Book )

3 editions published in 1978 in English and held by 6 WorldCat member libraries worldwide

Large, simply supported beams of temperate lake ice were found, generally, to yield significantly higher flexural strengths than the same beams tested in the cantilever mode. Data support the view that a significant stress concentration may exist at the fixed corners of the cantilever beams. Maximum effects are experienced with beams of cold, brittle ice substantially free of structural imperfections; for this kind of ice the strength difference factor, here attributed to the effect of stress concentrations, may exceed 2.0; that is, simply supported beams test a factor of 2 or more stronger than the same beams tested in the cantilever mode. In ice that has undergone extensive thermal degradation, the stress concentration effect may be eliminated entirely. Simply supported beams generally yield higher strengths when the top surfaces are placed in tension. This behavior is attributed to differences in ice type; the fine-grained, crack-free top layer of snow-ice which constituted up to 50% of the ice cover in the current series of tests usually reacted more strongly in tension than the coarse-grained crack-prone bottom lake ice.

The Canol Pipeline Project. A Historical Review by Herbert T Ueda( Book )

2 editions published in 1977 in English and held by 3 WorldCat member libraries worldwide

This report is a historical review of the Canol project, the first long-distance petroleum pipeline system constructed in the Arctic region of North America. The project was initiated during the early days of World War II when the military situation appeared critical. It was designed to supply the military need for fuel in the area, particularly Alaska, by exploiting the Norman Wells oil field in the Northwest Territory of Canada. The system was completed in April 1944 and operated for 11 months converting 975,764 barrels of crude oil into gasoline and fuel oil. Construction for the pioneering effort was difficult and costly. Considerable controversy plagued the project throughout; nevertheless, its completion proved that undertakings of such magnitude could be accomplished despite the formidable problems of the Arctic.

Movement Study of the Trans-Alaska Pipeline at Selected Sites by Herbert T Ueda( Book )

2 editions published in 1981 in English and held by 3 WorldCat member libraries worldwide

Eight sites along the trans-Alaska pipeline from the Denali Fault to Fairbanks were selected for pipeline and pipeline support movement studies. Four measurement surveys were conducted, starting before oil pumping operations began up to September 1978, to determine the lateral and longitudinal pipe movement due to the thermal expansion of elevated sections of the pipeline, the tilt of the vertical support members (VSM's), and the changes in relative elevation of the support crossbeams. A maximum lateral and longitudinal motion of the pipe of 13 3/8 in. and 2 13/16 in. respectively were measured up to September 1978. Tilt data for 180 VSM's showed little change over a one-year period, with only 5 VSM's tilting more than 0.5 deg. Relative elevation measurements showed insignificant changes for two sites compared over a one-year period. Comparisons of our data with as-built elevations at 8 sites show a few large differences that cannot be readily explained. In general the pipeline and its supports, at least at the sites studied, show minimal movement and activity. (Author)

Haines-Fairbanks Pipeline: Design, Construction and Operation( Book )

1 edition published in 1977 in English and held by 2 WorldCat member libraries worldwide

This report, one of a series, is intended to provide a background for the analysis and evaluation of new pipelines being built in cold regions. Topics discussed include the initial design, construction, testing, operation and maintenance of, and modifications to, the 8-in. pipeline from the deep water port of Haines to military installations at Fairbanks, Alaska. The 626-mile multi-product pipeline began operation in 1956. The results of a corrosion survey completed in 1970 indicated that extensive renovation would be required to continue operations, and the section from Haines to Eielson Air Force Base was closed in 1973.
