Abstract: A new method of generating local ice pressures is proposed through field iceindentation tests. This method can statistically produce intermittent peaks of local ice pressures at independent ice failure zones of the ice/structure interface. It applies the shot noise model (WEISS, 1977) which is used to generate continuous time streamflows with sharp peaks and recessions. A spatial distribution of compressive strength of natural ice sheet is also considered, based on experimental data from ice sampled at Lake Saroma. The ice load calculation results as well as the contact ratio between ice sheet and structure are shown by combining the time histories of local ice pressures generated by the shot noise model for each independent ice failure zone.
