Foundations and Excavations in Decomposed Rock of the Piedmont Province
The five papers in this volume deal with foundations and excavations in the Piedmont Province of the USA. This is a region underlain by very old metamorphic rocks that are overlain by...

Spanning the Seas
A proposed structural scheme, called the V�tower system, could cross vast stretches of water with record length spans yet use only conventional materials. An example is a bridge proposed...

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...

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...

Scour Prevention at Bridge Piers
Laboratory experiments are described in which attempts are made to eliminate local scour at bridge piers using submerged vanes and pier collar. The submerged vanes direct bed load toward,...

The Scourge of Scour
Among 86 bridge failures from 1961 to 1976, more were caused by scour than by earthquakes, wind, structural problems, corrosion and accidents combined. Scour is the erosion of a stream...

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...

Design of Bridge Piers Against Ship Collision
Design rules for unprotected bridge piers, using uniform safety requirements, are proposed. The selection of an appropriate design vessel is based on a risk assessment model which uses...

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...

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...

Surveying for Scour
The public works engineer never knows exactly how many bridge piers and abutments are undermined by erosion due to scour. Massachusetts Department of Public Works needed a rapid method...

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...
