Model Studies of Ice Interaction with the U.S. Army Ribbon Bridge.

The performance of the U.S. Army's floating Ribbon Bridge in an ice-filled waterway is investigated in a model study. Conditions when ice-blocks could be expected to jam behind the bridge are outlined using available instability theories. It is shown that current theories do not accurately desc...

Description
Summary:The performance of the U.S. Army's floating Ribbon Bridge in an ice-filled waterway is investigated in a model study. Conditions when ice-blocks could be expected to jam behind the bridge are outlined using available instability theories. It is shown that current theories do not accurately describe block instability throughout the range of expected block thicknesses. Bridge deployment doctrine is outlined as it relates to the winter environment. Ice forces on the bridge are discussed along with ways to minimize the change of ice building up behind the bridge.
