Abstract: A four-year field program was undertaken to measure ice loads on hydroelectric structures. The highest load (of 210 kN/m [14.3 kips/ft]) resulted from a combination of water level and ice temperature changes. At the two sites where ice temperature changes were the sole ice-load generating mechanism, the maximum load was 69 kN/m (4.7 kips/ft). The ice loads acting on the dam face were comprised of the initial load in the ice prior to any changes in water level and ice temperature (termed. the residual load), the increase in load associated with rises in ice temperature, and the increase in load · associated with water level changes. As these are quite different ice load-generating mechanisms, each load component needs to be considered separately.
