基于脉冲射流的小浪底水库人工异重流输沙方法探讨

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。

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

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.
