| 摘 要： | 浑水异重流是泥沙运动的一种形式,对水库和港池航道等泥沙淤积具有重要影响.许多专家学者都对浑水异重流进行了深入全面的研究,尤其是关于水库浑水异重流运动规律的研究,取得了丰富的成果.但是,这些研究成果大多是基于稳定流条件得出的,而对于潮汐条件下浑水异重流的研究非常少.本文分别对稳定流和潮汐条件下异重流的研究进展和研究方法进行了分析、归纳和总结,并指出了研究工作中的不足和今后需进一步研究的方向.

| Abstract: | Sediment-induced density current is one form of sediment movement,which has much influence on sedimentation in reservoirs,harbor basins and waterways.Many scholars have delved into sediment-induced density current,and made many achievements especially about density current in reservoirs,but the study of sediment-induced density current under the action of tides is few.The paper illustrates the methods and defects of the existing study and suggestes the direction of future study. |
