针对渠系建筑物涵闸下游水流特点,采用一种适合于低佛氏数消能的新型消能结构一拱网消力池,并对通辽西辽河灌区洪淤渠、孟家段干渠和八一水库泻洪洞采用拱网消能的工程实例进行了分析。结果表明,与普通消力池相比.拱网消力池的池长可缩短50%以上,池深可减少约30%,且消能率可提高20%以上,一般比普通消能措施可节省工程造价30%以上。
針對渠繫建築物涵閘下遊水流特點,採用一種適閤于低彿氏數消能的新型消能結構一拱網消力池,併對通遼西遼河灌區洪淤渠、孟傢段榦渠和八一水庫瀉洪洞採用拱網消能的工程實例進行瞭分析。結果錶明,與普通消力池相比.拱網消力池的池長可縮短50%以上,池深可減少約30%,且消能率可提高20%以上,一般比普通消能措施可節省工程造價30%以上。

The arch net-floor stiling pond are used to many low water head hydraulic structure according to hydraulic property of canal system structure.several engeneerings examples such as hongyu canal of xiliao riv- er, mengjiaduan canal,bayi reservoir are analyzed.the results show that the long of arch net-floor stiling pond is 50 per sent of general stiling basin and the depth and engineering cost can be decrease 30 per cent compared with general stiling basin. The rate of energy dissipation are increased 20 oer cent
