Puget Sound Alluvium: A Challenge in Design of Pile Supported Port Facilities with Dredged Slopes
The geotechnical investigation, evaluations, and recommendations for the Port of Seattle Terminal 18/20 Improvement Project are described and compared with observed performance during...
Underwater Compaction of Sand Fill During Placement
A system and related equipment have been developed, and tested on a recent dredged fill project, to compact sand, either clean or with limited silt, in lifts several feet in thickness...
Construction Materials for Civil Engineering Projects
The materials of construction in use today have grown in number, increased in complexity, expanded in application and multiplied in utilization over those in use just a short time ago....
Salvaging the Zilwaukee
In 1982, construction of the Zilwaukee Bridge in Michigan was disrupted when the launching truss failed to hold a precast concrete segment near Pier 11N, severely deflecting the cantilever...
The Mile High Dream
For the 1986 Tall Buildings Conference in Chicago, a group of experts studied the implications of a mile high skyscraper to be built of concrete. It is 500 ft square at the base, designed...
Asphalt Pavement Modifiers
