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...
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...
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...
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....
Massive Ice Detection by Earth Resistivity
This paper presents two case histories utilizing remote sensing earth resistivity equipment to target subsurface massive ice locations. In one case, a number of probe locations were made...
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...
Coal Mining in Alaska's Interior: Problems and Solutions
The Usibelli Coal Mine located in Healy, Alaska is currently the largest operating coal mine in the state of Alaska. The mine has recently increased production to nearly 1. 7 million tons...
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...
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...
Spring Stiffness for Beam-Column Analysis of Soil-Structure Interaction Problems
The objective is to provide a simple means of analytically combining a two-dimensional foundation with a beam-column structure so that the procedure can be used for preliminary design...
Dynamic Soil-Structure Interaction by the Boundary Element Method: A Comparison Study
A comparison study of three Boundary Element Method approaches is attempted on the basis of a typical three-dimensional, dynamic soil-structure interaction problem. The vertical transient...
Interactive Design of Reinforced Concrete Foundations
A new, highly graphical foundation design program, FOUNDATION-3D, provides the designer with a variety of easy to use foundation design tools in a flexible interactive environment. It...
Self-Adapting CAD Software
An approach for enhancing CAD and other interactive software is described. The goals of the approach are bifold, to customize complex programs which employ computer graphics, and to improve...
An Interactive Shell for Batch Processors
Many programs have been and are currently being developed in which the input data files or associated databases must be developed independently of the main program. This paper describes...
Animated Response of Dynamic Systems
Understanding how a simple structural system responds to a dynamically applied load is a difficult concept for most students to grasp. The fundamental mathematical theory of this behavior...
The Mexican Earthquake: A Firsthand Report
The Mexican earthquake of September 19, 1985 was most peculiar, because of the combination of its intensity, regularity, and duration. No other earthquake has had an intensity of IX, at...
