Abstract: An 11-year investigation was conducted regarding static ice loads on hydro-electric dams. Field measurements were made at 8 sites over a 9 year period. Algorithms were developed to predict ice loads along the length of the dam; and on stoplogs and gates. An environmental model was developed to predict ice thickness, snow depth, slush, and ice temperature. Ice temperature changes and thermal loading events were hindcasted for 73 stations in Manitoba, Ontario, and Quebec. An Ice Load Design Guide was made that: (a) synthesized the results, and; (b) established a statistical database which allowed loads to be calculated using a computer program for: (a) the long face of dam, and; (b) stoplogs. The measured loads show reasonable agreement with the predicted ones with respect to magnitude and return period.
