Expert System for Driven Pile Selection
Selection of driven piles for deep foundations is a complex process. Many subjective factors enter into the decision of which pile to select, making experience an important factor in proper...

Three-Dimensional Nonlinear Study of Piles and Simplified Models
In a recent study the authors examined the effect of the nonlinear behavior of soil on the axial and lateral response of one or two piles due to monotonic and cyclic pseudodynamic loading...

An Expert System for Civil Engineering Applications
Civil engineering is a field where experimental knowledge has no substitute. Making experts' knowledge explicit and documenting and transferring it can have a great impact...

Do Simplistic Methods of Foundation Design Produce Reliable Foundations?
Many foundations today are designed using deterministic (single value) analysis techniques which do not reflect the natural variability of soil properties. If the standard deviation and...

Settlement of Footings on Sands?Accuracy and Reliability
Twelve methods of estimating settlements of footings on sand were evaluated by comparing calculated settlements with measured settlements. Each of the methods was evaluated in terms of...

Dynamic Testing to Predict Static Performance of Drilled Shafts Results of FHWA Research
The paper describes the preliminary results of recent research sponsored by the FHWA on predicting by relatively economical dynamic methods, the static capacity and performance of drilled...

Group Effect in the Case of Downdrag
A summary of the various techniques available to calculate downdrag forces on pile groups is presented. In light of all these existing techniques, a simplified method is recommended. An...

Foundation Evaluation of Barkley Dam for Seismic Analysis
An in-situ site investigation was performed at Barkley Dam, KY to gather essential information on the stratigraphy and nature of the foundation soils. From this information the site was...

Hurricane Hugo's Effect on Marina Structures
The author has visited over twenty-five sites along the South Carolina coast and in Puerto Rico to ascertain the effects of Hurricane Hugo on marina facilities. Types of structures evaluated...

Foundations and Breakaway Walls of Small Coastal Buildings in Hurricane Hugo
After Hurricane Hugo a survey of damage to small, coastal buildings was conducted in North and South Carolina. The performance of elevated foundations, breakaway walls and foundation cross...

Targeted Public Outreach
The Minerals Management Service (MMS) has a public affairs program whose goal is to inform the public about the functions of the MMS. An overview of the program is discussed in this article....

Reassessing the 3-Mile State/Federal Boundary
The allocation of state versus federal authority offshore is critical in determining the complexion and pace of OCS oil and gas development. Yet, recurring drilling moratoria indicate...

An Offshore Borehole Mining Experiment: Its Operational and Environmental Implications
The Continental Shelf Division of the Marine Minerals Technology Center (MMTC), conducted a miniborehole mining experiment offshore Georgia in June 1990. A remote placer drill developed...

A Model for Evaluating Outer Continental Shelf (OCS) Oil and Gas Exploration Plans
The North Carolina OCS Office in consultation with emergency response planning & management (erp&m) developed evaluation matrices for use in evaluating the adequacy and...

OCS Oil and Gas Off South Florida?Developing a Consensus on the Facts
Drilling for oil and gas in the area north of the Florida Keys has been a contentious issue over the last several years. To help provide an understanding of the effects of exploration...

The Pacific Northwest OCS Task Force?Evolution and Status
The Pacific Northwest Outer Continental Shelf (OCS) Task Force was established in January of 1989 to provide advice to the Secretary of the Department of the Interior (DOI) on issues related...

The Los Penasquitos Lagoon Foundation?A Study of Citizen Involvement in Coastal Wetland Management
The Los Penasquitos Lagoon Foundation was organized in 1984 with the assistance of the California Coastal Conservancy to help resolve conflicts among land owners, citizens, state resource...

Mitigation for Offshore Development/Fishing Conflicts
Three case studies, WestGold gold dredging offshore Nome, Alaska, Endicott Causeway off Alaska's North Slope, and Platform Irene offshore California, show that project related...

The Role of Mitigation Funds in Mitigating Residual Impacts
Environmental Impact Reports/Statements (EIR/S) for four offshore oil and gas projects with onshore components in Santa Barbara county have identified potential impacts to coastal and...

Artificial Headland and Submerged Groyne for a Beach Improvement Project
The design approach that was used to determine the length and elevation of a submerged groyne as well as a system for providing adjustment to the elevation of the submerged groyne is presented....
