Centrifugal Modeling of Ice Forces on Single Piles
The ice forces and ice floe failure mechanisms associated with an ice sheet surrounding a vertical cylindrical pile were evaluated. A test system was developed to model ice forces in gravity...
Lightweight Fill Helps Albany Port Expand
Lightweight aggregate was used as a soil fill in the reclamation of a marine terminal at the Port of Albany, New York in order to stabilize the dockside area. Gravel-filled steel sheet...
Artificial Islands
Artificial islands constructed from gravel fill have become a preferred approach to drilling for oil in hostile Arctic environments. These man-made islands are being built to serve as...
Yukon River to Prudhoe Bay Highway � Lessons in Arctic Design and Construction
Construction of roads on muskeg over perennially frozen subsoils is becoming increasingly common in the arctic and subarctic regions of North America due to recent emphasis on development...
Frost Heaves�� A Major Dilemma for Ice Arenas
The ice sheets of three arenas in Minneapolis-St. Paul have had frost heaves ranging from seven to eleven inches (0.2 to 0.3 m). Proper design should prevent frost from penetrating the...
