通过对新疆迪那河五一水库工程导流兼排沙洞水工模型进行泄流试验,研究悬栅消力池的型式、体型、数量等参数对消能效果的影响,最终确定悬栅消力池内加17根栅条、池后采用1/8进行变坡的优化方案。试验结果表明：悬栅的设置,改善了消力池内水流的流态,降低了池内的最大水深。在设计水位下,设置悬栅后使消力池内最大水深由原来的19.4 m下降到17.3 m,并且消力池内各项水力指标均满足设计要求。
通過對新疆迪那河五一水庫工程導流兼排沙洞水工模型進行洩流試驗,研究懸柵消力池的型式、體型、數量等參數對消能效果的影響,最終確定懸柵消力池內加17根柵條、池後採用1/8進行變坡的優化方案。試驗結果錶明：懸柵的設置,改善瞭消力池內水流的流態,降低瞭池內的最大水深。在設計水位下,設置懸柵後使消力池內最大水深由原來的19.4 m下降到17.3 m,併且消力池內各項水力指標均滿足設計要求。

Based on the hydraulic model tests for the diversion and desilting tunnel of Wuyi Reservoir in Xinjiang,the effects of the suspended-grid plunge pool＇s type,size,quantity and other parameters on energy dissipation are studied in detail,and ultimately the optimal scheme is determined,in which 17 grids are added in the pool and the variable slope with 1/8 is adopted after the pool.The test results show that with the set of suspended grids,the flow pattern in the pool would be improved,the maximum water depth in the pool would be reduced from 19.4 m to 17.3 m,and the hydraulic indexes in the pool could meet the requirements of the design.
