2007 – Comparison of New Zealand and North American dam anchoring practices

Stephen McInerney, Donald A. Bruce and John Black

An historical database of North American dam anchoring experience has been recently assembled in the United States. This database clearly shows the historical development of dam anchoring technology, particularly with regard to corrosion protection practices over four decades. The results of this research are significant to dam owners worldwide because of the number of examples in the database.

The paper describes New Zealand experience with dam anchoring against the background of the historical practices in North America and the main conclusions drawn from the United States research.
