AbstractAfter eight winters of the extensive monitoring program of the interaction between ice features and the piers of the PEI Confederation Bridge, a detailed video and sonar data analysis of all the events including interactions between first year ice ridges and the bridge piers has been done. This paper introduces the results of this video and sonar data analysis related to the interaction of the underwater part with piers. A statistical study concentrates on the effect of the keel and the consolidated layer geometric properties, such as the keel depth, the keel width and consolidated layer thickness, on the load resulting from the above mentioned interaction. Moreover, the relation between the load on one side with the geometric properties of the keel underwater part and the ice ridge velocity is introduced. The real fullscale observations and results presented in this paper can be taken as a key to the development of an accurate load model.
