Historic Dam Rehab: Handle with Care
A growing number of dams across the U.S. are aging and in need of rehabilitation, but can they be brought up to current codes without compromising their historic integrity? Improved methods...

Geotechnology: An Environment of Change
Today's contaminated materials�soil and water�have been investigated and analyzed by geotechnical engineers for a long time. No other branch of engineering is better positioned,...
Seattle's Good Neighbor Policy
The West Point wastewater treatment plant in Seattle sits on a spit of land jutting into Puget Sound. Close by is Discovery Park, a haven for nature lovers, located on a bluff above the...
Pile Test for Earthquake Repair
Load testing for existing concrete piles was specified as part of a seismic retrofit at the Port of Oakland after the Loma Prieta event. The Port wished to use heavier cranes at cargo...
Landfill Liners from Top to Bottom
Since EPA began requiring geomembrane liners in 1982, liner system components have multiplied rapidly. At the same time, there has been a movement toward relatively large, sophisticated,...
Anchors in the Desert
The Southwest desert isn't usually thought of as a hotbed of seismic activity, but earthquakes have occurred there. And if Arizona's Stewart Mountain Dam, a double-curvature...
Pumping Oil, Treating Soil
Oil was discovered on hilltop land in Signal Hill, Calif., in 1921, setting off one of the most wild land rushes the state has ever seen. Some 70 years and 20,000 oil wells later, the...
Excavating, OSHA-Style
When the Occupational Safety and Health Administration implemented its new, tougher trenching guidelines in July 1990, the agency opened the door for inventive excavation techniques. Contractors...
Probabilistic Risk Analysis of TLP Tether Fracture
A stochastic model for fatigue crack growth and final fracture of TLP tethers is formulated. Model updating through in-service inspection is included. The integrity of the cracked tether...
Progressive Failure Probability of Soil Slopes Containing Geologic Anomalies
The variability in the redistribution of stress during sliding failure of a slope is first studied. Presence of a geologic anomaly is shown to affect the failure path pattern and likelihood...
Autocorrelation Functions for Offshore Geotechnical Data
Autocorrelation functions are described. Data from several North Sea sites are analyzed with respect to the vertical and horizontal autocorrelation of a number of soil properties. Based...
Bayesian Updating of Axial Capacity of Single Pile
The paper outlines a Bayesian technique to update predictions of pile driving and axial pile capacity on the basis of pile driving records. The approach enables one to systematically account...
Probabilistic Evaluation of the Performance of Axially Loaded Bored Piles
Probabilistic evaluation of single slender elastic elements, bored piles, in a multi-layered soil system without noticeable displacement of the soils are considered. The numerical analyses...
Seismic Hazard Estimation in the Eastern U.S.
Probable seismic hazard is generally estimated considering five elements: 1) seismicity; 2) source radiation; 3) wave propagation (attenuation); 4) site response; and 5) ground failure....
Largest and Characteristic Earthquakes in the U.S. East of the Rocky Mountains
A new statistical procedure is proposed for the estimation of maximum earthquake magnitude M in intraplate regions. Starting from a historical catalog of events and a seismotectonic classification...
Seismic Ground Motion and Attenuation Relationships
A key element in the assessment of seismic hazard is the estimation of how energy from a given earthquake is affected by crustal structure along the propagation path. There are recognized...
