Static Ice Loads On Hydro-Electric Structures - Summary Report, Ice Load Design Guide, and Ice Load Prediction Computer Program

A ten-year project was undertaken in which field programs were conducted over a nine-year period from 1991-92 to 1999-00 to: (a) measure the loads in the ice sheet near the dam; (b) measure the load distribution between a gate and pier, and: (c) compare the loads on wooden and steel stoplogs. Parallel work was conducted to develop analytical predictors for ice loads. An environmental model was developed which compares well to the measured data.

An Ice Loads Design Guide was produced, synthesizing the results obtained from various previous years, and establishing a statistical database that allows ice loads to be calculated in a coherent format for:
(a) The long face of dam for various locations, water level change operational regimes, return periods and confidence levels. These ice loads would be applicable to dam safety analyses.
(b) Stoplogs for various design cases.
