Hydro Systems Evaluation on Personal Computers
The programs for selecting the equipment and determining the average annual energy have been separated from the detailed financial analysis. The BASIC language was selected for the first...
Microcomputers as Productivity Aids for Small-Scale Hydroelectric Projects
Off-the-shelf software that has been used to improve productivity includes Computer-Aided-Design-and-Drafting (CADD) systems, spreadsheets, project managers, word processors, and communications...
Computer Modeling and Applications
A series of programs is available to evaluate the hydrology, compute the capacity to generate energy, establish unit costs, analyze penstock surge pressures, and simulate ramping rates....
Three-Dimensional Plotting in Dam Potentials
Hydroelectric development is important to many basins in the western United States. Topographical studies are normally used to arrive at sites to be chosen for further investigation of...
Wind Loads on Electrical Transmission Structures
Guidelines for structural loads on electrical transmission structures were prepared by the American Society of Civil Engineers' Committee on Electrical Transmission Structures....
Innovations in Prestressed Concrete Structures
Prestressed concrete poles are probably the best choice for most transmission line structures. They have many advantages over structures made from other materials for both engineering...
Bolted Connections for Steel Towers
Laced electrical transmission towers require on-site assembly. Consequently, the number of bolts and pieces are important considerations in the total cost of the structures. ASTM A394(1)...
TLMRF Research Initiatives
The research initiatives of the EPRI (Electric Power Research Institute) structural development project RP2016-03 are described. The interrelationship of these initiatives with cosponsored...
Strain Gaging and Data Acquisition at the TLMRF
Strain gages are the major source of data for the TLMRF (Transmission Line Mechanical Research Facility) research program. Measurement of member loads and bending moments in lattice towers...
Special Pile Foundations for a Coastal Permafrost Site
The design of the plant's foundations had to address several challenging geotechnical conditions. These included (1) 'warm' (close to 32 degree F)...
Costs of Truck Related Highway Damage to Alaska
The cost of pavement damage to the State of Alaska for truck traffic continues to be a very controversial topic. There is no simple answer since this cost is dependent upon pavement strength,...
Hot Sand for Improved Traction on Icy Roads
Experiments were performed to determine if heating sand prior to spreading it on icy roads would improve the skid resistance of the road more than cold sanding. Tests were made on a full-scale...
Building Foundation on Thawed Soil and Permafrost
The site of a planned 10,000 square foot State Youth Facility in Bethel, Alaska was found to be underlain by discontinuous permafrost. This paper describes the geophysical and geotechnical...
Stabilization of a Permafrost Subsidence in the Airport Runway at Bethel Alaska
During the construction of the extension to the Bethel Airport runway in 1969, it was necessary to construct a fill across a small gully. The subbase material in the gully contained some...
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...
A Self-Refrigerated Gravel Pad Foundation for Large Thermal Loads
Design criteria for a proposed power plant at Thule Air Force Base, Greenland, involved both large thermal loads from the diesel engines and large static loads from an eight foot thick...
Development of a Self-Heating Thermal Probe for Saline Permafrost
Geothermal modelling and prototype testing are described to support the development of a self-heating thermal probe. This has application for in-situ determination of the amount of unfrozen...
Installation of Thermistor Strings in Test Borings: A Comparison of Methods and Results
Several test borings were instrumented with two thermistor strings, one inside and one outside an air-filled PVC casing to compare readings of both thermistor strings and the stability...
Monitoring Techniques for Thermosyphons
Two-phase thermosyphons used for passive soil refrigeration are monitored using a variety of techniques ranging from visual infrared scanning to measurement of internal pressures. Methods...
Ground Temperature Monitoring Cominco's Red Dog Project
Procedures are available in the literature for estimating subsurface thermal characteristics of foundation soils in cold regions using published climatic characteristics for a given area....
