Document Type: Journal Paper


This paper describes the principal methods employed in evaluating the observations from the large (36 foot diameter) tunnel test section at Garrison Dam and the major results therefrom–including load on the temporary support ribs, magnitude and distribution of load on the permanent concrete lining, and a better understanding of the inherent safety of a circular lining provided by ring action. Some new analytical methods are presented and their possible application is discussed.
