Piedra Del Aguila�New Hydropower for Argentina
Construction commenced in early 1985 on the 1. 0 billion Piedra del Aguila Hydroelectric Project on the Rio Limay about 1200 km (750 mi) southwest of Buenos Aires, Argentina. The project...
Sherman Island Hydro Cofferdam
The design and construction of an eight hundred foot long by sixty-five foot high cofferdam is discussed. The cofferdam was located to permit major renovation of the existing downstream...
Evaluation of Liquefaction Potential of Anderson Ranch Dam
This paper contains a description of a liquefaction evaluation of the alluvial foundation soils at Anderson Ranch Dam, which was performed as part of the USBR's program of...
Thermal Monitoring of Leakage Through Dams
The technique involves very accurate temperature measurement at shallow depth below the reach of the surface diurnal cycle. Temperatures respond to subsurface water movement (with advective...
Seismic Isolation System for a Floating Dry Dock
The seismic isolation system consists of two dolphins, each a relatively large-diameter cantilevered steel pipe pile anchored in Franciscan rock, and buffered connections to the floating...
Design of Drilled Piers Subjected to High Overturning Moments
The results are presented of a research study directed at improving the state-of-practice, and resulting foundation economy, in the design of laterally loaded drilled pier foundations...
IEEE/ASCE TransmissionStructure Foundation Design Guide
The American Society of Civil Engineers' (ASCE) Subcommittee on Foundation Design for High-Voltage Transmission Structures was formed in October 1976. The purpose of the Subcommittee...
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)...
Adfreeze Strength of Ice to Steel Pipe Piles as a Function of Temperature
A study was initiated to determine the adfreeze bond strength between steel pipe piles and freshwater ice as a function of temperature. Tests were conducted at an average strain rate of...
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...
35-Year-Old Foundations, Thule Air Base, Greenland
In February 1951 the secret project 'Blue Jay' to construct the base began. Timber piling were used in the foundations of boilers, generators, and other heavy...
Design and Monitoring of an Ice Drill Pad
An ice pad was sucessfully designed and built to provide a suitable foundation for an exploratory drill rig in the National Petroleum Reserve of Alaska in early 1985. Design considerations...
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...
An Economical Approach to Receiving Coal by Rail in the Sub-Arctic Environment
During the period 1983 to early 1985 a multimillion dollar coal transfer facility was designed and constructed in Seward, Alaska. The facility transfers coal from rail cars to temporary...
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...
Geotechnical investigation: Cominco's Red Dog Mine Facilities
The siting of major facilities associated with development of the Red Dog Mine Complex in Northwestern Alaska on relatively warm permafrost soil and rock presented geotechnical engineers...
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...
Bearing Capacity Calculations for Piles in Permafrost
Small-scale model piles frozen in various soils were tested at constant rates of displacement and constant load. The derived values were used to calculate the maximum allowable stress...
Sheet Pile Interlock Behavior: A Moving Contract Problem
The finite element method is used to analyze the behavior of sheet pile interlocks subjected to an uniaxial pull test. The thumb and finger of the interlock provide three contact points...
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...
