Logistics for Structures Sealifted to the Arctic
Sohio has successfully pioneered the development of the Prudhoe Bay reservoir by sealifting prebuilt oil processing facilities from the lower 48 states. The experience thus gained is being...

Centrifugal Modeling of Ice Forces on Single Piles
The ice forces and ice floe failure mechanisms associated with an ice sheet surrounding a vertical cylindrical pile were evaluated. A test system was developed to model ice forces in gravity...

Structural Solutions for the Enhancement of Gravity Foundations on Very Soft Arctic Soils
Very soft soils in several offshore Arctic areas cause a major concern in the design of gravity foundations, particularly in view of the high magnitudes of ice loads. Preliminary studies...

Pile Creep Designs for Frozen Layered Profiles
A concept of relative creep stiffness suitable for the evaluation of the long-term, uniform creep behavior of non-ice type, frozen soils is presented. This concept extends the current...

Creep Rate Analysis of Pile Load Test Data
The uniform creep behavior of five driven piles and one slurried pile based on pile load test data are presented and analyzed. The incremental static load tests carried out by ARCO, Alaska...

Research Challenges in Frozen Ground Pile Design
A fairly recent pile design analysis is reviewed. The influence of such factors as temperature, salinity, loading, etc. on frozen ground pile design is pointed out. Since many facets of...

Planning Aspects of the Woodward Corridor LRT Preliminary Engineering Project
The efficient deployment of any major project requires careful planning of the management, scheduling and budgeting activities associated with its implementation. The Woodward Corridor...

Evaluation of Structures by Dynamic Load Testing
The Frequency Sweep Method for the evaluation of structures by dynamic load testing was developed by the senior author. It is a non-destructive testing (NDT) method that was originally...

Standards for Pile Load Tests in Permafrost
A requirement exists to establish standard procedures for conducting pile load tests in permanently frozen soils. The methods outlined in the ASTM Standards for piles in thawed soils do...

Attenuating Creep of Piles in Frozen Soils
Results of several long-term creep tests of piles in frozen soils are analyzed; the primary or attenuating creep is predominant in most cases. For effective design of pile foundations...

Snow Effects on Pile Design Temperatures
The construction of North Slope aboveground pipelines and gathering lines is generally from snow workpads constructed proximate to existing access roadways. The pile support centerline...

Geotechnical Behavior of Underreams in Pleistocene Clay
Enlarged bases are often constructed in cylindrical drilled-and-cast-in-situ foundation elements (footings, bored piles) to increase their capacity. Enlarged bases that are cut mechanically...

Review of Repeated Axial Load Tests on Deep Foundations
A review of the literature is presented on the axial capacity of deep foundations subjected to repeated loads. Data are summarized on anchors, driven piles, and drilled shafts. In general,...

Watershed Management in 1985
Today's technology in subalpine watershed management is based on carefully designed watershed experiments beginning with Wagon Wheel Gap in 1909. Subsequent advances in process...

Timber Bridge Decks
The portion of the nation's 500,000 bridge decks that are made of timber has been declining for years, as the old timber ones on secondary road bridges are rebuilt, in most...

Diagnosis of Wastewater Treatment Processes
This paper presents an approach to the development of an expert system for aiding the operation of an activated sludge wastewater treatment facility. The expert system incorporates a diagnostic...

Foundations in Permafrost and Seasonal Frost
The papers in this volume cover the following subject areas: A method that utilizes a decision matrix diagram for selecting the most suitable and economical foundations for construction...

Dewatering--Avoiding Its Unwanted Side Effects
The undesirable side effects that sometimes occur when dewatering for construction or mining are presented, including: ground settlement due to dewatering; deterioration of timber piling;...

Drilled Piers and Caissons II
Drilled piers or caissons, also called drilled shafts or bored piles, have long been a very cost effective foundation solution for many soil profile and load situations. A distinct advantage...

Nantucket's Endangered Maritime Heaths
Heaths, though common in northern Europe, are of disjunct distribution and limited development on the east coast of North America. In contrast, Nantucket Island, Massachusetts supports...
