姚河坝水电站以库代池泥沙冲淤控制研究

Study on desilting control by adopting reservoir instead of pond for the Yaoheba hydropower station

姚河坝水电站以水库代替沉沙池进行沉沙和冲沙 ,可取消地下沉沙池。通过改变水库运用方式 ,合理控制水库泥沙淤积和泄空水库冲沙 。

By adopting reservior instead of pond for trapping an d flushing sand, the desilting pond of the Yaoheba hydropower station can be can celed. The long-term valid regulating storage required by design can be ensured by modifying the reservoir operation mode, rationally controlling silt depo sit and drawing down reservoir level for flushing silt.
