Model Test of Ice-Structure Interaction

Abstract

Different scales of model tests for investigating ice-structure interaction due to ice crushing have been conducted, and successful experiences and conclusions obtained from previous tests are summarized. On the other hand, the uncertainties within current methodology of ice-structure interaction model tests are discussed. Considering the nature of dynamic ice loads, several main aspects which should be taken into account during design of model tests are analyzed, including layout of the test system, application of scaling laws, and techniques of making model ice sheet, etc. Decision can be made for each of these aspects according to objective of the test, and based on this viewpoint, a small scale model test system was designed and constructed, a series of model tests were conducted and the ice-structure interaction processes which are the same as prototype phenomenon were observed.
