ABSTRACT

This paper reviews the modelling of ice-hydraulic structure interaction with the specific purpose of determining the loads that can be generated on stationary structures due to thermo-mechanical processes in the ice and dynamic effects in the interaction process. The paper specifically addresses two types of ice loadings, those that are generated due to interaction of ice covers and hydraulic structures and those generated due to impact of the ice covers with hydraulic structures. The first category of problem is examined by using finite element modelling of a temperature sensitive creep process and the latter employs discrete element methods which account for fragmentation of the ice floe during the impact. The time dependent evolution of the interactive load is examined via the computational schemes.
