冯家山水库排沙试验模拟研究

Simulation Research on Sediment Flushing of Fengjiashan Reservoir

冯家山水库是一座位于多沙河流上的大(II)型水库,异重流排沙已较为成功地解决了水库淤积问题。试验通过修建局部坝前水库,观察了异重流在水库模型中的掺混过程及浑水水库的形成过程,并定性地得到了坝前含沙量垂线分布。

Fenjiashan Reservoir is a large (Ⅱ) reservoir located on a sediment-laden river. The sediment deposition of the reservoir has been controlled successfully by the method of sediment flushing with density current. The blending process of the density current and the forming process of the turbid water reservoir are observed through building the reservoir before dam, and the vertical distribution of sediment before the dam is obtained in the experiment.
