Design Evaluations in Support of Offshore Facilities and Gravel Islands in the Arctic
Development of oil resources in Northern Alaska has involved the design of nearshore and offshore facilities and structures in the Beaufort Sea and Prudhoe Bay in water depths ranging...
Testing of Admixtures for Seabed Strengthening
Samples from several offshore soil borings in an area of the Beaufort Sea were subjected to laboratory testing to determine the applicability of this method. The soils were mixed with...
Design of Modular Structures for the Arctic
Sohio's efforts to continue the production and initial processing oil from Prudhoe Bay, Alaska requires additional production enhancement equipment on the Alaskan North Slope...
Lessons Learned From Examination of Membrane Roofs in Alaska
During 1984 and 1985 airborne infrared roof moisture surveys were conducted of membrane roofs at Army installations in Alaska. Many of these roofs were also visually inspected and cored...
Snow Load Design for Colorado Mountains
During the past decade, Colorado mountain construction has experienced a period of rapid growth. New ski resorts and other business developments have resulted in many new facilities. For...
Ester West Slide?A Case History
An 80 foot high embankment was benched into graphitic schist permafrost on a north facing slope approximately 25 miles west of Fairbanks, Alaska. Soon after construction approximately...
Reinforced Roads Bridging Voids
A mathematical model was developed to design a pavement section reinforced with a geotextile or related product to span a void. A full scale field test was conducted to verify the model....
Characterization of the Dalton Highway Foundation Soils
A case study is presented of the landform-based probabilistic-statistical route geotechnical characterization of natural foundation soils along the Dalton Highway. Landforms were mapped...
An Economical Approach to Receiving Coal by Rail in the Sub-Arctic Environment
During the period 1983 to early 1985 a multimillion dollar coal transfer facility was designed and constructed in Seward, Alaska. The facility transfers coal from rail cars to temporary...
Cold Regions Features of the Whittier Access Tunnel
A feasibility study and cost estimate has been prepared for a vehicular tunnel which would form a portion of a highway between the town of Whittier, Alaska and the east side of the Kenai...
Long Term Performance of the Goldstream Creek Bridge
In 1964 the Alaska Department of Transportation and the U. S. Army Cold Regions Research and Engineering Laboratory initiated a cooperative study which in the long-term generated a significant...
A Thermal Analysis of Pavement Thawing
This research focuses on identifying the spring thawing period for the purpose of timing load restrictions on low to medium volume roads in frost-susceptible areas. Cases evaluated include...
Ice Cover Research?Present State and Future Needs
Presentation reviews, at first, a number of problem areas in ice engineering, such as the determination of vertical and horizontal forces floating ice covers exert on fixed structures,...
Terrain Analysis From Space Shuttle Photographs of Tibet
Several Space Shuttle missions obtained false color and large format, high resolution, black and white stereo photography at an approximate scale of 1:800,000. In addition to available...
Anchorage Taps Eklutna Lake for New Water Supply
The 170 million Eklutna Water Project will furnish water to Anchorage, Alaska by the summer of 1988. The project consists of an 8,500-foot long diversion tunnel, 6 miles of 54 to 60-inch...
An Overview of Cold Region Considerations for the Design of the Eklutna Water Project
The paper presents a brief overview of cold regions considerations that were considered during the design of the various elements of the Eklutna Water Project in Anchorage, Alaska. The...
Water Treatment Facility Design for a Glacial Lake
