Design of Large Steam Turbine-Generator Foundations
This report is a guide for engineers who are responsible for the design and analysis of large turbine-generator foundations. A description of the various components of turbine-generator...
Hydraulic Structures on Piles
Many hydraulic structures built in the early 1900's were founded on piles. Today, when these structures are analyzed as 'pile-supported', the analyses...
Underwater Inspection of Hydraulic Structures
Improvements in diving equipment, and underwater testing and instrumentation devices in recent years have increased the value of underwater inspections and reduced the cost. This paper...
Parametric Analysis of Concrete Gravity Dams using Finite Element Analysis
More sophisticated means of analyses have been investigated to determine the accuracy and applicability of conventional methods to a range of parameters affecting stability. This paper...
Local Scour Under Waves Oblique to Current
Local scour around a cylindrical pile subjected to waves oblique to current was experimentally studied in a laboratory flume with a wave generator. The mode of wave-current interaction...
Low Head Dam Safety Studied with Hydraulic Models
Use of physical models to study the hydraulic jump or submerged roller action created as water overflows low head dams provides an opportunity to develop design criteria for various structure...
Rehabilitation of the SF Calawah River Bridge
The failure of a 4-span reinforced concrete bridge in Washington State initiated a study that ultimately led to a unique method of bridge rehabilitation. Severe scour resulted in settlement...
Innovative Approaches to Bridge Pier Foundation Design
As a part of a Value Engineering change proposal the pier foundations for the US-31 bridge over the St. Joseph River and floodplain near Niles, Michigan were re-designed. The varying soil...
Dynamic Simulation of Foundations on Winkler Subgrade
The objective of this paper is to present a dynamic simulation of foundations on Winkler subgrade. The analysis is based on a direct simulation procedure. The structures have been modeled...
Lateral Impedance of Contact Pile Foundations
The static and dynamic lateral impedance of pile foundations for which there is continuous contact between the bottom of the pilecap and the underlying soil is investigated. A parametric...
The Wet Look
The collapse of the Schoharie Creek bridge drew attention to underwater inspection. Underwater inspection of bridges gives engineers a better understanding of the condition of the bridges....
CAD Maps Ocean Floor
This article describes the Navy's use of computer aided design to map-out a 250 sq mi expansion of an anti-submarine warfare training facility in St. Croix, Virgin Islands. Three hundred...
Strategic Planning in Transportation: Uses and Abuses
Strategic planning makes sense because its foundations are in good economic principles. Firms that don't do it are practicing a 'let's live for today'...
Taipei Trade
The appearance of this building is remarkable�so were the cost savings. A design change form rigid shear walls to a ductile frame helped keep construction of Taipei's World...
Shake-Proof Dams
Seismic trouble spots in California and along the Pacific Coast usually get the most publicity. But many people don't realize that Wyoming, Illinois, South Carolina, Utah...
New Deep Foundations Cut Costs
Two European innovations in deep foundations are highly competitive in cost, time and material. They are the barrette (slurry wall segment) and the bored pile/caisson which is then grouted...
Another Geotech Import: Deep Soil Mixing
A technique called deep soil mixing (DSM), imported from Japan, has been used to stabilize an existing dam foundation. When the Bureau of Reclamation discovered that Jackson Lake Dam had...
The Pelican, Alaska Hydroelectric Station
In August 1983 Pelican Cold Storage directed KPL to install a new 600 kW turbine, synchronous generator, controls and penstock transition section. This new equipment was to fit upon the...
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...
