淤泥质河口建闸后需要解决泥沙淤积的问题,它制约着河口的综合利用。本文就我国淤泥质河口挡潮闸引起的闸下淤积和清淤措施研究成果进行了综述。首先归纳了我国主要建闸河口闸下淤积类型,多数学者根据潮波变形理论和不平衡输沙理论对闸下淤积的力学机理和控制因素进行分析,解释和预测河口闸下淤积的基本特征和发展趋势,提出不同类型的建闸河口防淤减淤措施。最后指出目前研究中的不足和以后应进一步加强研究的问题。 Muddy estuaries need to solve the problem of sedimentation after the sluice is built, which restricts the comprehensive utilization of estuaries. This paper summarizes the research results of sediment deposition and dredging measures caused by sluice tidal gates in China’s silt estuaries. First of all, the sediment types in the main gates of sluice gates are summed up. Most scholars analyze the mechanics and control factors of siltation under sluices according to the theory of tidal wave deformation and unbalanced sediment transport, and explain and predict the siltation characteristics under the sluices. Development trend, proposed different types of Jianzha estuary anti-siltation measures. Finally, it points out the shortcomings in current research and the problems that should be further strengthened in the future.
