Highway Design in 3-D
Limitations in the flexibility and intelligence of commercial roadway design packages led Hart-Freeland-Roberts, Inc., Brentwood, TN, to write its own highway design software. From the...

Beyond Push-Button GPS
In 1993, the U.S. Air Force Space Command will complete its deployment of 24 satellites for the Global Positioning System, affording 3-dimensional positions and velocities 24 hours a day...

A Monumental Task
The geotechnical consultants, structural engineer and contractor combined to overcome difficult soils, underground subway structures and buried utilities when building the foundations...

Appropriate Technology for Flood Warnings
Computers can help protect cities and other developed areas by enhancing flood warning systems, but smaller communities may not be able to take advantage of their sophistication. The Corps...

Taming Tornado Alley
Some structures�such as nuclear power plants�need complete protection from tornadoes regardless of the high costs of design and construction. Public facilities need protection too, but...

Expert Systems: Ready to Hit the Road?
Expert systems, programs that take the rules a person uses to solve a problem and encodes them into a computer, are starting to get serious examination from DOTs around the country. The...

Water Management Under Drought Conditions an Overview of Practices by Federal Agencies
The management of water resources under drought conditions is a diverse topic which has received added emphasis recently as a result of prolonged droughts in parts of the United States....

New Cruise Terminal for San Francisco
A new international Cruise Terminal is being developed at Pier 30-32 in San Francisco, to replace present inadequate facilities at Pier 35. The Cruise Terminal will be developed as part...

Signing Systems: Directional, Identity, and Graphic Systems for the Port of Long Beach
The authors have developed (in conjunction with Port staff) a revolutionary roadside communication system for The Port of Long Beach. The system includes: Renamed piers for easier understanding...

On-Off Terminal Ship-to-Rail Transfer
The intermodal situation of U.S. ports is still evolving, and port planners will be facing difficult decisions regarding IM Configurations. This article was intended to assist 'perplexed'...

NYK Line's new terminal at the Port of Los Angeles (photograph below) features innovative design and advanced terminal operating system integration....

Port of Portland's Berth 601 Floating Dock
The Port of Portland's facilities, being located on the Columbia and Willamette Rivers, are subjected to extreme water level fluctuations. Over the years, the Port has used floating docks...

Analysis of a Wharf for a Container Terminal
A balanced combination of sophisticated computer programs was employed to model the soil strata, foundation and structure of a wharf for a new container terminal in the Port of Topolobampo,...

Deep Water Container Wharf & Crane Foundation
A deep water anchored steel bulkhead and a parallel-independent low-profile, pile supported crane rail foundation with special stowage areas are discussed from soils investigation, through...

Case Study ? Elliott Bay Marina Floating Moorage
The recently completed Elliott Bay Marina project in Seattle is one of the larger projects of this type in the country, with 1196 slips ranging from 32 feet to 60 feet, a floating fuel...

Batter Piles and the Seismic Performance of Pile-Supported Wharves
This paper discusses the role of batter piles in the seismic performance of wharves, based on the results of a nonlinear soil-structure interaction analysis of a pile-supported wharf with...

Riprap Design in Marine Terminals
Navigation vessels in otherwise quiescent waterways sometimes generate forces that require stabilization of the bed or banks. Since riprap is an accepted and dependable means to armor...

Non-Intrusive Rayleigh Wave Measurement System for Soil Profiling in Ports
Accurate shear wave velocity profiles have been long recognized as essential data to evaluate the dynamic response of soil deposits and soil-structure interaction under earthquake and...

Proposed Seismic Design Method for Piers and Wharves
Current seismic provisions of the 1991 Uniform Building Code (UBC-91) and the 1983 AASHTO Seismic Design Specifications (AASHTO) are compared as they relate to piers and wharves. An alternate...

A Computational Berthing Model for the Design of Fender Systems
