在多水年份,仅有少部份洪水通过水电站的水轮机,而大部份洪水是经专设的泄水建筑扬排泄至下游的消能设备的。在水量丰富的河流上泄洪时,不能总是保证消力池安全运行。萨扬舒申斯克水电站不仅要求泄水建筑物的技术方案新颖,而且将以这类泄水建筑物的典型实例载入泄水建筑物的史册。 In the multi-year years, only a small proportion of the floods passed through the hydroelectric power station’s turbines, while most of the floodwater was drained to the downstream energy-dissipating facilities via dedicated drainage structures. It is not always possible to guarantee the safe operation of a stilling basin when discharging floodwater on a river that is rich in water. The Sayan Shushenskaya hydropower station not only requires a novel technical solution to the drainage structures, but also loads the history of the drainage structures with typical examples of such structures.
