| 摘 要： | 向家坝水电站泄洪消能具有高水头、大单宽流量、多泥沙的特点,泄洪消能布置要考虑发电、通航、防洪和拦沙等因素的影响.多股多层水平淹没射流是一种新型消能型式,可降低消力池出池水流的波动、底板压强及临底流速,具有流态稳定、消能效率高、雾化低、适应性强等特点,较好地解决了向家坝水电站泄洪消能问题,为同类工程及环境影响要求较高的工程提供了重要参考,同时也丰富了泄洪消能工的型式.

| Abstract: | The flood discharge with energy dissipation of Xiangjiaba Hydropower Station has a high water head,large unit discharge and sediment-laden characteristics;energy dissipation arrangement to be considered for power generation,navigation,flood control and sediment retention and other factors.A new type of energy dissipation,multi-horizontal submerged jets can reduce the fluctuation of water flow stilling,intensity of pressure and bottom velocity of plunge pool;it has stable flow,high energy dissipation efficiency,low fogging,well-adapted and other characteristics;so as to effectively solve the issue of energy dissipation for Xiangjiaba Hydropower Station.It provides an important reference for similar projects and projects with low environmental impact requirements,also enriches the types of energy dissipation. |
