The Vertical Pressure Distribution on Structures Subjected to Rubble-Forming Ice

摘要

A laboratory test program has been performed on ice loading through pressured broken ice. The results have applications to both structures and ships in Arctic regions. The work was performed by measuring the loads on a segmented planar structure for various loading conditions. The variables included ice strength, ice thickness, ice density, ice/structure friction and angle of inclination of the structure. Vertical distributions of loads, point of resultant load application and overturning moments have been examined. A comparison of extrapolated peak pressures show excellent agreement with full-scale measurements on the Gulf Canada's arctic structure Molikpaq.
