Centrifuge Model Testing with Dynamic and Cyclic Loads
This paper examines the use of small-scale tests on centrifuges to study a wide range of problems in soil dynamics - including machine foundations, structures and explosion effects. The...

Uplift Behavior of Shallow Soil Anchors?An Overview
An overview is presented of the static uplift (tensile) behavior of shallow anchors used for foundations in soil. Basic anchor types are described, and their general installation and behavioral...

Uplift Capacity of Shallow Offshore Foundations
Soil failure under upward loading is investigated by experimental laboratory tests. The problem of uplift capacity is considered in terms of effective stresses in soil skeleton and pore...

Transmission Tower Foundations in Weathered Rock
A case history is presented which discusses the siting, design and construction of the tower foundations for a transmission line in southwest Alaska. The project, completed in 1983, consists...

New Safety for Old Dams
Shortly after the Phase I inspection program conducted by the U.S. Army Corps of Engineers in 1978-81, the Pennsylvania legislature authorized $300 million for repair of dams, ports and...

The Hydroelectric Barge
The nation's inland waterway system includes many low head locks and dams, with undeveloped hydropower potential estimated in excess of 1,100 MW. For most of these dams, hydro...
