【摘要】：對(duì)滲流輸沙的形式、泥沙起動(dòng)的臨界條件和泥沙輸移模型三個(gè)問(wèn)題進(jìn)行了總結(jié)。目前的研究成果眾多,有基于經(jīng)驗(yàn)數(shù)據(jù)的總結(jié)、有關(guān)于理論方法的推導(dǎo),但總體來(lái)說(shuō)各種成果的適用性都有局限。各種成果的差異的原因需要深入研究,從而找出更精確的理論方法。對(duì)于二維滲流以及非飽和滲流作用下的泥沙運(yùn)動(dòng)問(wèn)題需要在以后的研究中得到加強(qiáng)。
[Abstract]:The form of seepage and sediment transport, the critical condition of sediment incipient and the model of sediment transport are summarized. At present, there are many research results, including summary based on empirical data and derivation of theoretical methods, but in general, the applicability of these results is limited. The reasons for the differences in results need to be studied in depth to find out more accurate theoretical methods. The problem of sediment movement under the action of two-dimensional seepage and unsaturated seepage needs to be strengthened in the future.
