The CBR Test Applied to Processed and Compacted Snow
The processes used during the past two decades to improve the snow bear a modest resemblance to conventional flexible pavement construction, thus the field CBR (California Bearing Ratio)...
Soil Strength Recovery Using a Clegg Impact Device
The research described in this paper uses the Clegg Impact Device to determine the relative strength of a soil, and describes how this information can be used to develop the strength recovery...
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...
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...
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,...
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...
Alyeska Reroutes Trans-Alaska Pipeline at MP 200
This paper discusses the 1985 wintertime repair/reroute to the Trans Alaska Pipeline System (TAPS). The rerouted pipe was approximately 4000 feet long and cost approximately 27 million....
Repair Welding of Arctic Offshore Structures and Vessels
This paper describes the welding procedure development for repair or field modifications of offshore drilling structures and vessels made with several different steel grades produced for...
Finite Element Modelling of Cold Regions Concreting
Finite element heat transfer computer programs are discussed in regard to their use in modelling cold weather concreting. The concrete material properties required for input to the finite...
F.E.M. Analysis of Mobile Arctic Caisson Island With Stochastic Material Properties
The paper examines how soil uncertainty influences the short term settlements and stresses of the Mobile Arctic Caisson on the original sea bed. Utilizing a two-dimensional plane strain...
Geomembrane Liner Performance in the Arctic
A geomembrane liner must be selected not only on the basis of its chemical compatibility with the substance to be contained, but also on the basis of its physical performance characteristics...
The Transport of Crude Oil Under Saline Ice
A mathematical model was developed to describe the forces acting on an oil slick under saline ice in the presence of a water current. The model was verified through a set of laboratory...
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...
The Evolution of a Factory Insulated Piping System
This paper reviews the developments over the past fifteen years in a factory insulated high density polyethylene piping system that has become a standard for sewage and water piping systems...
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,...
Waterfront Stabilization Project, Kaktovik, Alaska
This paper discusses an innovative 384-foot treated-timber cribwall design utilized to control rapidly accelerating thermal erosion and establish a roadway along the bluff on the Beaufort...
Legal Concerns in Cold Regions Engineering and Construction
For a variety of reasons the potential for the imposition of liability and the potential for comparatively large damage claims is greater in cold regions. It is the purpose of this paper...
Proposed Operation of an Expert System for Analyzing Construction Project Risks
The principal problem for the construction project manager is selecting the most effective response when project progress deviates undesirably from targeted objectives. Optimally, the...
Sheet Pile Interlock Behavior: A Moving Contract Problem
The finite element method is used to analyze the behavior of sheet pile interlocks subjected to an uniaxial pull test. The thumb and finger of the interlock provide three contact points...
