A short review is presented of the literature on thermal ice pressure against extended hydraulic structures such as dams. Some of the methods suggested for the computation of ice loads caused by temperature changes are reviewed. As a means of comparison measurements of thermal ice pressure and empirical values used at present for estimating these loads are referred to. Ice forces on structures are determined either by the environmental driving force or by the force to fail the ice sheet and move the ice around the structure; which ever is the least. State-of-the-art techniques for predicting these forces on fixed, rigid structures are presented. The modes of interaction between ice and structure are discussed, and the properties of both ice and structure are seen in the context of interaction. The key parameter of the ice is the dependence of crushing strength on loading rate, in particular the inverse relationship that exists for a certain range and gives rise to negative damping. A review of the buckling analyses of floating ice sheets is presented. The theory used is that of a beam or plate on an elastic foundation.
