Abstract

Studies on the effect of the sink-&>float-type ice boom (SFIB) in ice flow control and measurements which prevent SFIB from burying in sand A. Imaizumi", F. Kara*, H. Saeki* & K. Enoki' °Nishimuragumi Co. Ltd, Sakaemachi, Yubetsu, Mombetsugun, Hokkaido, 199-64 Japan ^Department of Civil Engineering, Hokkaido University, Japan ^Akita National College of Technology, Japan This is a report on the results of detailed experiments aimed to clarify: (1) the effect on ice floe control of the Sink-and-Float-type Ice Boom (SFIB) and (2) the optimal sectional form of SFIB which may prevent SFIB from becoming buried in sand when it sinks. The SFIB consists of a number of floating bodies linked by steel wires whose ends are tied to piers. The SFIB sinks to the sea bottom when the floats are filled with water, but floats to the sea surface when the floats are filled with air, preventing ice floes from intruding into the harbor.
