消能建筑物能最大限度的消除水库下泄洪水的能量,以起到保护水库工程和下游河道的安全,常见的消能方式有挑流消能、底流消能和面流消能3种。赤沙水库的消能方式比较特殊,采用二级消能,第一级为不常见的跌流消能,第二级为常见的底流消能;以此为例,分析计算了两种方式下消力池的尺寸,以期在工程运行中检验。
消能建築物能最大限度的消除水庫下洩洪水的能量,以起到保護水庫工程和下遊河道的安全,常見的消能方式有挑流消能、底流消能和麵流消能3種。赤沙水庫的消能方式比較特殊,採用二級消能,第一級為不常見的跌流消能,第二級為常見的底流消能;以此為例,分析計算瞭兩種方式下消力池的呎吋,以期在工程運行中檢驗。

Energy dissipation structure can maximize the elimination of reservoir flood of energy to protect the reservoir and downstream channel safety engineering.The common energy dissipation contain three types of energy dissipation including ski-jump,hydraulic jump and surface regime.Energy dissipation of Chisha reservoir is a special way using level 2 of energy dissipation.The first level is uncommon drop flow energy dissipater and the second level is the common hydraulic jump energy dissipation.Taking it as an example,the size of stilling pool of the two ways were analyzed and calculated for checking in similar engineering projects.
