Soil-Pipeline Interaction During Ground Movement
The problem of the elastic interaction is examined between a pipeline or a group of connected flexible connected pipelines and the surrounding soil medium, which is induced by ground movement....
Technical Considerations for Beaufort Sea Pipelines
The development of Beaufort Sea fields requires construction methods and equipment for pipeline installation and trenching providing a balance between safety, reliability, and economy....
Analysis of Liquefaction Potential of Hydraulically Placed Subsea Berms
The use of hydraulically placed sand for the construction of artificial islands for hydrocarbon exploration in the Beaufort Sea has necessitated detailed geotechnical evaluations of their...
Fracture Theory for Nonhomogeneous Brittle Materials with Application to Ice
Brittle heterogeneous materials generally fracture with a dispersed zone of microcracking at the fracture front. The deformation and failure of these materials can be described by a nonlocal...
Spalling and Buckling of Ice Sheets
The effect of local eccentricity in the vertical direction on the magnitude of compressive strength of wide ice sheets is studied theoretically. Two new failure modes are identified: indentation...
Thaw Settlement as a Result of Permafrost Deterioration
An overview is given of floor and footing failure as a result of deterioration of permafrost. Consideration of causes for the deterioration and methods of repair are addressed in general...
Earth Pressure on Underground Concrete Pipe in a Field Test
The cause of cracking at the sheetpile extraction in concrete pipes buried by the open excavation method was investigated by loading tests on the pipe and a field test carried out by Osaka...
Earth Pressure on Underground Rigid Pipe in a Centrifuge
A series of centrifugal model tests on underground pipes that simulate the actual construction process were carried out to investigate the earth pressure concentration onto the pipe (particularly...
Maintaining a Natural Gas Pipeline in Active Landslides
This paper deals with a pipeline section on both sides of Douglas Pass in west Colorado. Landslide activity in the area has been causing considerable problems and disruptions of the pipe...
Methods for Reliability Analysis of Water Distribution Networks
A detailed review of the literature reveals that there is currently no universally accepted definition or measure of reliability for water distribution networks. The purpose of this paper...
Seismic Pope Support Construction Practices
During the mid 1970's the regulatory agencies controlling the design and construction of nuclear power plants began to demand stricter adherence to already existing codes...
Structural Retrofit for Nuclear Power Plants
Retrofitting of nuclear power plants is a major concern these days. Recent rulings of regulatory agencies have affected most of the generating plants in some way. The lessons learned from...
Modifying Piping Systems During a Plant Outage
This paper describes methods to reduce problems in design and planning of modifications to piping systems during a nuclear plant outage. Significant differences between original design...
The 1984 novel
Classification of Human Errors
Error control should be a primary part of any risk control strategy. Classification of errors may serve as a basis for the systematic analysis to eliminate the causes and to reduce the...
Concepts and Methods in Reliability-Based Structural Optimization
This paper presents an overview of the major concepts and methods used in reliability-based structural optimization. New formulations related to multicriteria optimization are developed....
Seismic Analysis of Horse Creek Dam, Hudson, Colorado
On April 8, 1981, six days after a Richter magnitude 4. 0 earthquake, inspectors from the Colorado State Engineer's Office discovered a small crack in outboard side of Horse...
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...
Filters and Leakage Control in Embankment Dams
In the practice of earth dam engineering there has been some doubt that downstream filters could be relied upon completely to control and seal concentrated leaks through impervious dam...
Earth Dam Seepage Control, SCS Experience
The U. S. Department of Agriculture's Soil Conservation Service (SCS) designs and administers construction of a large number of small- or medium-sized dams. SCS experience...
