摘　　要：对以往黄河高含沙洪水"揭河底"冲刷的研究成果进行了归纳和总结,从"揭河底"冲刷发生的机理、河床边界条件、水沙条件、判别指标、试验研究、数值模拟等有关方面给出了已有的研究成果,并提出今后"揭河底"冲刷需要继续深入研究的问题:①黄河"揭河底"冲刷发生时的水沙条件、河床边界条件和河床淤积物分层问题;②黄河"揭河底"冲刷的判别条件和指标问题。The paper sums up the outcomes of study on 'river bottom tear off' scour of hyper-sediment concentration floods of the Yellow River occurred before,provides the existing research results on the related aspects of mechanism of 'river bottom tear off' scouring,channel boundary condition,silt-discharge condition,discriminant index,test and study and numerical simulation and puts forward the following issues that needs further study in the future: a) silt-discharge condition,channel boundary condition and channel deposit stratification when 'river bottom tear off' scour occurred and;b) discriminant index and criter,Chinaion for 'river bottom tear off' scour of the Yellow River.
