The ability to predict ice pile-up loading and load transfer characteristics will facilitate design of Arctic artificial islands, platforms, jetties, and other large structures with the potential to generate pile-ups under appropriate ice-structure interaction conditions. In this paper, following a general review of the basic concepts published by the authors and others in the area of rubble pile formation and force transmittal, extensions of the theory are presented and results are compared with previously published work. The extensions include the incorporation of heretofore unpublished probability density functions to represent slope angles of individual ice pieces idealized through the use of multi-modal failure theory. A significant dependence of interaction load on the properties of the probability density function is found. In addition, the effect of pile-ups on ice-structure interaction loads is evaluated utilizing techniques based on the theories of granular and cohesive media to evaluate ice pile-up load capacities and load transfer characteristics. Numerical results are generated and compared with relevant related theories.
