TVA Cuts Deep Slot in Dam, Ends Cracking Problem
In 1972, cracking in the concrete dam at TVA's Fontana project embarked TVA on a four-year program of investigation, analysis and repair. Thermal expansion in the downstream...
$70 Million for Dam Inspection
In 1972, Congress passed the National Dam Inspection Act, requiring the U.S. Corps of Engineers to inspect and inventory all dams in the United States; but few dams were inspected. Then...
Dam Anchored to Foundation to Withstand Floods
Federal Power Commission Order No. 315 required a safety review of Conowingo Dam and Powerhouse by an independent board of consultants. As recommended by this board, a study was made of...
New River Gorge Bridge: World's Longest Steel Arch
For 45 years, the Bayonne Bridge had reigned as the world's longest steel arch bridge. No longer. The New River Gorge Bridge in West Virginia has a steel arch spanning 1700...
Geotechnical Practice for Disposal of Solid Waste Materials
The papers for this conference are grouped under the themes of four of the general sessions: 1) Geotechnical properties affecting disposal and utilization; 2) utilization in dams, embankments,...
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,...
New River Gorge Bridge: World's Longest Steel Arch
The world's longest steel arch bridge, spanning the New River Gorge Bridge in the south central area of West Virginia, is scheduled to be completed in Sept. 1977. The main...
Polymerization of Concrete Fights Cavitation
The techniques and materials used for the repair of concrete are many and varied. The repair at Dworshak Dam utilized epoxy resins, dry pack mortar, fibrous concrete and a new technique,...
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:...
Nambe Falls Dam�First Mechanically Prestressed Concrete Dam in U.S.
An unusual combination of a curved earth embankment, a concrete gravity thrust block, and concrete thin arch prestressed with embedded vertical flat jacks has created Nambe Falls Dam,...
The Evaluation of Dam Safety
Proceedings of the Engineering Foundation Conference on the Evaluation of Dam Safety, held in the Asilomar Conference Grounds, Pacific Grove, California, November 28 December 3, 1976....
Award-Winning ASCE Papers in Geotechnical Engineering 1950-1959
Papers, Discussions, and Closures from ASCE Proceedings and Journal of the Soil Mechanics and Foundations Division
This collection of papers covers a broad range of relevant issues in geotechnical engineering. Topics include capillary phenomena in cohesive soils, final foundation treatment at Hoover...
Inflatable Dam Regulates River Level
Inflatable dams are economically feasible for maintaining a required constant water elevation on rivers and streams where flooding poses problems. Puncture resistant material, inflated...
Inverted Filter Stabilizes Soil, Stops Erosion
The inverted filter concept was invented by Karl Terzaghi to prevent dams from failing by water piping through the foundation. Laboratory and field testing have refined the necessary specifications...
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...
The Le Grande Hydroelectric Development
The James Bay Hydroelectric Project, presently under construction in northern Quebec, is one of the world's largest energy developments. Four major powerhouses are planned...
Responsibility and Liability of Public and Private Interests on Dams
Proceedings of the Engineering Foundation Conference, Responsibility and Liability of Public and Private Interests on Dams, held in Asilomar Conference Center Grounds, Pacific Grove, California,...
Numerical Methods in Geomechanics
Proceedings of the Second International Conference on Numerical Methods in Geo-mechanics held at Virginia Polytechnic Institute and State University, Blacksburg, Virginia, June, 1976....
Difficult Dam Problems�� Marginal Spillway Stability
In l965 the Corps of Engineers began a program of inspection and reevaluation of its older dams to determine if they are satisfactory based on present day standards. The study of the spillway...
Corps Guidelines for Dam Safety Inspection Need Revamping
A protest (1) that Proposed Guidelines for Safety Inspection of Dams, Federal Register, August 1974, pp. 31334-31346, ignores well-publicized conclusions of a preexisting ASCE task committee...
