Abstract: Using of a scaled experiment in the ice model basin is a necessary component of investigations into complicated interaction of various engineering structures with ice. An important role of ice model tests has been indicated in issued draft version of international standard ISO/DIS 19906, which is coming into force in 2010. Meantime, existing ice basins use different technologies for preparation of model ice and model ice features. Furthermore, there are distinctions in measuring techniques for model ice properties determination, in applying instrumentation, as well as in the results interpretation and full-scale extrapolation. A purpose of the presented studies is to establish a base for harmonization of definitions of model ice properties and to develop unified interpretation of the measurement results. The paper studies procedural peculiarities of determination of the main ice strength properties that are to be simulated in the ice model basin – flexural strength and compressive strength, as well as first-year ridge keel properties – angle of internal friction and cohesion.
