PS 5 Sewage Lagoon Embankment Stabilization
In 1981 an embankment containing a three-cell wastewater treatment lagoon was constructed adjacent to the northern edge of the Pump Station 5 gravel pad on the Trans Alaska Pipeline System....
Freeze-Thaw Effects on Clay Covers and Liners
The properties of clay covers and liners used for containing solid waste materials are highly susceptible to environmental stresses. Even when clay layers are protected from drying, freezing...
Experimental Study of Adfreeze Heaving of Augered Caisson Footings
In order to establish the required depth of augered caisson-type footings in cold regions and their optimal design against adfreeze heaving, an experimental field investigation has been...
The Thermal Regime Surrounding a Longitudinal Edge Drain
Newton Airfield in Jackman, Maine, was constructed in 1986 to perform as a drained pavement system. The drainage design consisted of a permeable base course with a longitudinal edge drain...
Numerical Analysis of Frost Shields
The term 'frost sheilding' has been used to describe the practice of using flat stock rigid insulation materials burial above a water or sewer pipe to reduce...
Computer Predictions of Thaw Beneath Gravel Embankments on Warm Permafrost
A computer model was used to simulate the freeze-thaw effects of gravel embankments on warm permafrost typical of south-central Alaska using a one-dimensional finite-difference code, FREZ1D....
Treatment of Unstable Foundation Areas in Alaska's Pavement Management System
In the State of Alaska Department of Transportation and Public Facilities Pavement Management System (PMS) unstable foundation areas are defined as sections of roadway that experience...
Analysis of Soil-Stress Cell Interaction
Static loading experiments conducted on a soil stress cell embedded in a sand are presented. Stress cell performance was evaluated by comparing the indicated stress against the expected...
Earth Walls: Making the Right Choice
Earth walls are retaining walls where the ground assumes a load-bearing role. These walls either support compacted earth (embankment-type reinforced compacted earth walls such as Doublewal...
Leachate Flow from an Experimental Fly Ash Landfill
Combustion of coal in large-scale utility boilers produces an ash by-product which is often stored in open landfills. An experimental fly ash landfill was constructed by Pennsylvania Power...
Cold Regions Engineering
This proceedings consists of papers presented at the Cold Regions Engineering Specialty Conference held in West Lebanon, New Hampshire from February 26-28, 1991. The papers cover nine...
Fixing Foundations
Conventional underpinning or pilings are still the most common construction methods used to strengthen foundations, but new grouting techniques are giving engineers some fresh alternatives....
Dallas' Flood Caverns
Dallas' North Central Expressway floods during heavy rains, but the dense development that helps create excessive runoff also precludes large detention ponds. The high-quality,...
Beyond Engineering: The Politics of Maracaibo
The Lake Maracaibo Bridge in Venezuela was built in 1959. It ranks as one of the largest and longest bridges in the world at the time it was built and contained the longest concrete cable-stayed...
Strain Distribution in Fault Zones and Fluid Flow
Field and laboratory studies have shown that mechanical shearing in fault zones produces a repeatable fabric that changes with increasing shear strain. In the brittle field of mechanical...
Computer-Assisted Geometric and Kinematic Analysis of Subsurface Faulting in the Vicinity of Yucca Mountain, Nevada, Using Balanced Geologic Cross Sections
Computer-assisted geological cross section balancing methods are used in the geometric and kinematic analysis of subsurface structures in the vicinity of Yucca Mountain, Nevada, including...
Microwave Measurements of the Water Content of Bentonite
The theory of operation of microwave coaxial resonators is described. Sample preparation and the application of resonator techniques to the measurement of the permittivity (dielectric...
Effect of a Low-Permeability Layer on Calculated Gas Flow at Yucca Mountain
Yucca Mountain is being studied to determine its suitability as a location for a high-level nuclear waste repository. The mountain is a steep-sided linear ridge which is underlain by a...
Research Program to Develop and Validate Conceptual Models for Flow and Transport Through Unsaturated, Fractured Rock
As part of the Yucca Mountain Project, our research program to develop and validate conceptual models for flow and transport through unsaturated fractured rock integrates fundamental physical...
Distribution of Rubidium, Strontium, and Zirconium in Tuff From Two Deep Coreholes at Yucca Mountain, Nevada
Variations in concentrations of trace elements Rb, Sr, and Zr within the sequence of high-silica tuff and dacitic lava beneath Yucca Mountain reflect both primary composition and secondary...
