Design of Tension Member Insulated Anchor for Arctic Pipelines
This paper explores the latest development in above-ground waterflood pipe anchors currently being used on the SOHIO operated portion of the Prudhoe Bay Oil Field. The objective of the...
Hot Sand for Improved Traction on Icy Roads
Experiments were performed to determine if heating sand prior to spreading it on icy roads would improve the skid resistance of the road more than cold sanding. Tests were made on a full-scale...
Design and Monitoring of an Ice Drill Pad
An ice pad was sucessfully designed and built to provide a suitable foundation for an exploratory drill rig in the National Petroleum Reserve of Alaska in early 1985. Design considerations...
A Self-Refrigerated Gravel Pad Foundation for Large Thermal Loads
Design criteria for a proposed power plant at Thule Air Force Base, Greenland, involved both large thermal loads from the diesel engines and large static loads from an eight foot thick...
Development of a Self-Heating Thermal Probe for Saline Permafrost
Geothermal modelling and prototype testing are described to support the development of a self-heating thermal probe. This has application for in-situ determination of the amount of unfrozen...
Installation of Thermistor Strings in Test Borings: A Comparison of Methods and Results
Several test borings were instrumented with two thermistor strings, one inside and one outside an air-filled PVC casing to compare readings of both thermistor strings and the stability...
Ground Temperature Monitoring Cominco's Red Dog Project
Procedures are available in the literature for estimating subsurface thermal characteristics of foundation soils in cold regions using published climatic characteristics for a given area....
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...
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...
Moisture Effects on Extruded Polystyrene Insulation
The amount of moisture within the insulation was determined by carefully weighing each sample and then measuring its volume. Two methods of measuring thermal conductivity were used. The...
Insulation Performance Beneath Roads and Airfields in Alaska
Evaluations of the long-term thermal performance of installations in Alaska for frost heave control have included sampling and testing of the insulations to determine the retained thickness,...
Predictions of Thermally Induced Stresses in Thin Walled Grain Storage Bins Under Declining Ambient Temperatures
A generalized constitutive equation for cohesionless sands based on elasto-plastic theories is applied to a grain bin system. The validity of the theory is established through the finite...
Preliminary Seismic Risk Maps for Puget Sound
Ground shaking during Puget Sound earthquakes is characterized by irregularly shaped areas of high intensity ground motion, not all of which are correlated with soil type. Simulation of...
Seismic Acceleration Maps for Oregon
To evaluate the seismic hazard for the Corps dams in the Portland District, operating basis earthquakes (OBE) and maximum credible earthquakes (MCE) were established for seismic zones...
Earthquake Risks to Utah Water and Gas Systems
Designed to guide local earthquake hazard reduction programs, this study estimates direct aggregate earthquake damage to Davis and Salt Lake County utilities. For making these loss estimates,...
Seismic Risk Assessment for a Utility System
Presented is a procedure by which a utility could develop the probabilities for different levels of capital loss exposure for its system. The procedure relies on experience data obtained...
Seismic Risk Analysis of LNG Storage Tanks
This paper presents an approach to the seismic safety review of existing LNG storage tanks. The approach considers the seismic hazards from ground motion, surface fault rupture, and soil...
Seismic Risk Analysis System
The Seismic Risk Analysis System was developed to model the expertise of experienced engineers and researchers and to provide consultation to the users. The Seismic Risk Analysis System...
Precast Roofs for Blast Shelters
A shallow-buried reinforced concrete blast shelter has been constructed and dynamically tested at the U. S. Army Engineer Waterways Experiment Station (WES). Three thicknesses of precast...
