| 摘要： | Thirty two tests have been performed to determine forces associated with rubble ice moving against a model cable-moored platform, using the IIHR ice towing tank facility. The rubble ice was formed by freezing sheets of urea-doped ice to the appropriate thickness (5 or 25mm) and then breaking up these sheets using a pushblade on the motorized carriage. The broken ice was stored under insulation while further sheets were grown. For the tests, the rubble ice was spread into layers 5, 50 or 100mm thick. / Supplementary Notes: Sponsored by Hitachi Zosen Corp., Osaka (Japan)., Mobil Research and Development Corp., Dallas, TX. and Minerals Management Service, Washington, DC. / Availability Note: Product reproduced from digital image.
