基于脉冲射流的小浪底水库人工异重流输沙方法探讨

Research of Manpower Density Flow in Xiaolangdi Reservoir Based on Pulsed Jet

小浪底水库的调水调沙实践证明,异重流在水库形成后,可以在水下长距离运行,直到排出库外,达到排沙清淤的效果,但其发生的时间段短。能否研究出一种满足异重流产生和运动的条件,并且长期产生人工异重流的设备,成为解决小浪底水库淤积问题的关键。为此,提出了采用脉冲射流冲驱泥沙实现人工异重流的方案。

Dispatch of water and sediment in Xiaolangdi Reservoir proves that density flow could move a long distance underwater till got out. It could make sediment out of the reservoir, but the time of its continuity is short. That the equipment can produce manpower density flow for a long time is the key problem to solve sediment in Xiaolangdi Reservoir. This text puts forward a scheme to realize the manpower density flow by pulsed jet ship for scouring sediment.
