摘要
姚河坝水电站地下水沉沙地工程造价的约占整个工程造价的一半。通过改变水库运用方式,在保证水电站安全,正常运行的前提下,以水库代替沉沙池进行了沉沙和冲沙,则可取消地下沉沙地,大幅度降低工程造价,缩短电站建设工期。
The cost of the underground desilting pond of Yaoheba Hydropower Station accounts to about half cost of the project. The scheme of using reservoir instead of desilting pond for depositing and discharging sediment is studied. It is demonstrated by the study that the operation mode should be changed to ensure the performance and safety of the power station when using reservoir instead of desilting pond so that the project cost could be decreased and the construction period could be shortened by employing the scheme.
