摘　　要：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。The task after building the tidal barriers of the muddy estuaries is solving the silting problem; restricts the comprehensive utilization of the river mouth. This paper discussed and analyzed silting induced by tidal barriers and the measure of reducing silting. Firstly, it concludes the type of the deposition under the main estuary built with barriers. Many scholars analyzed mechanics mechanism and control factor of scour and silting downstream of tidal barriers according to the theory of tidal wave transformation and unbalance sediment transportation, and explained and forecasted the basic character and development trend downstream of tidal barriers, bring forward measures of different type in preventing and reducing silting. At last, it pointed out the shortage existed and the problem which call for further research.
