Behavior of the concrete dam of the Ust-Ilim hydroelectric station under operating conditions
Conclusions 1. The concrete dam of the Ust-Ilim hydroelectric station after 3-yr operation under design conditions is in a satisfactory state. The seasonally opening joints in three powerhouse sections worsen the static behavior of these sections and the seepage through them presents difficulties during operation. 2. The actual strength of the concrete of the dam is unjustifiably high, and for blocks of the interior region the impermeability is thrice greater than the concrete grade impermeability. The superfluous strength of the concrete is due to the high content of cement. 3. The state of stress of the dam and its contact zone is more favorable than according to the results of current static calculations. This is explained mainly by the technological depression of the upstream face and low uplift pressure. 4. The offset profile of the powerhouse sections should be calculated not only for the load of the hydrostatic pressure of the water of the upper pool but also for the temperature effects of the period of filling the reservoir.
