Abstract: The flood discharging rain and fog at Ertan hydropower station exerted harmful influence on operation of hydraulic structures which required better protection of downstream bank revetment. Test on flood discharging rain and fog was carried out and the protection analysis showed that the protection scope and method were sound and good effect was achieved, worthy reference.

摘要： 泄洪雾化是一种具有严重危害性的雾化水流，影响建筑物的正常运行。二滩水电站泄洪强度大，泄洪雾化范围和强度超过了设计预想，对下游护岸的安全防护范围提出了更高的要求。泄洪雾化试验结果及防护效果分析得出，二滩水电站泄洪雾化区的防护范围是适当的，防护方法是可靠的，这是我国首座超过200 m高拱坝泄洪雾化防护成功的例证，对其他高坝泄洪雾化的防护有很好的借鉴意义。
