摘要
对渗流输沙的形式、泥沙起动的临界条件和泥沙输移模型三个问题进行了总结。目前的研究成果众多,有基于经验数据的总结、有关于理论方法的推导,但总体来说各种成果的适用性都有局限。各种成果的差异的原因需要深入研究,从而找出更精确的理论方法。对于二维渗流以及非饱和渗流作用下的泥沙运动问题需要在以后的研究中得到加强。
Types of sediment movement,critical condition of sediment incipient,and the model of the sediment transport under seepage flow were summarized in this paper. Current studies are focused on the summary of the observed data and the theoretical derivation,but limited in the applicability. The differences within the current achievements are necessary to be studied in more detail so that the more accurate theory can be found.This review emphasizes that the sediment movement under two-dimension seepage flow and the unsaturated seepage flow are should to be strengthened in the future research.
