Kamburu Dam: Diversion Conduit Designed into Spillway Saves $1,000,000
Careful coordination of dam construction operation with river stages over several seasons, and a construction sequence that called for building the spillway, in effect, from the top down,...
Vibroreplacement and Reinforced Earth Unite to Strengthen a Weak Foundation
Two relatively new engineering concepts in the U.S. were successfully used to solve a difficult soils problem. A highway skirting Idaho's Lake Pend Oreille was built on a...
Channel Siltation Determined with Side-Scan Radar
Of the new electronic means to measure water depth, side-scan sonar is unusual in that it gives not just a cross-section of the bottom but a semi-3-D picture of the bottom surface. Experienced...
Teton Dam Failure
In June 1976, Teton Dam in Idaho failed. It was an earthfill dam 305 ft high. It failed by piping through the impermeable core of the dam. Among factors believed contributing to failure:...
Granular-Fill Dam Protected by PVC Membrane
The design and construction of the Minorca Tailings Basin Starter Dam sets a precedent for the use of plastic membrane for seepage control in the construction of earth fill dams where...
The Story of Cement, Concrete and Reinforced Concrete
When the dawn of history, man has sought for materials to cement stone and brick together. When rebuilding the Eddystone lighthouse in 1756, John Smeaton recognized ordinary lime morter...
Rock Engineering for Foundations & Slopes
Proceedings of a specialty conference on Rock Engineering for Foundations and Slopes, held in University of Colorado, Boulder, Colorado, August 15-18, 1976. Sponsored by the Geotechnical...
Concrete Replaces Steel in Offshore Coal-Loading Terminal
An open water coal-loading terminal off the east coast of Australia berths 100,000 dwt coal ships. The concrete caissons for the berth were constructed within a drydock and later a breakwater,...
Hydraulic Fill Dams/Earthquake Stability
The 1971 San Fernando earthquake near Los Angeles, Calif., generated concern for the stability of hydraulic fill dams. Two dams located near the fault were damaged severely. The shaking...
Can We Engineer Vocational Assessment and Counseling for Everyone�
Because guidance is costly and time consuming and because testing provides incomplete coverage of potential, psychologists have been trying to engineer new procedures to help people more...
Earth Retention by Drilled Reinforced Concrete Caissons
A hillside fill is stabilized by the construction of drilled reinforced concrete caissons. The fill supports a building which houses equipment important to a manufacturing process. Other...
Affirmative Action Toward Equal Opportunity
An employer does not satisfy his obligation to discriminate against minorities merely by hiring some of them. He must go further and see to it that those he hires are either qualified...
Improving Your Writing�� Part II
Whereas Part I on Improving your writing (Jan., '75) talked about how to find something to say, this article (Part II) focuses on how to say it clearly, simply, forcefully....
Interstate Squeezes through River Gorge
The Virgin River Gorge in northern Arizona, a designated wilderness area, now contains one of the most beautiful and spectacular segments of our Interstate Highway System. Interstate 15,...
Tackling Major Highway Landslides in the Tennessee Mountains
Interstate 40, running through Tennessee's rugged Smoky Mountains, has been damaged in several places by major landslides. As illustrated by several case histories in this...
Tunnel under Alps Uses New, Cost-Saving Lining Method
Contractors of the Tauerntunnel through the Alps, near Salzburg, Austria, encountered very bad geology�� heavily distorted, preloaded rock under an overburden up to 3,300 ft (1,000-m)...
International Air Transportation
Worldwide events are swiftly presenting increasingly complex challenges to the international air transportation industry. This conference will confront some of these challenges in a search...
