摘　　要：六垛南闸下游引河近年来淤积日益严重,虽数次清淤仍未能从根本上缓解。通过分析六垛南闸下游引河淤积的原因,有针对性地提出了入海口建坝、合理开闸泄水和闸址下移这三类减淤措施,并利用流体力学和水沙运动理论,辅以数值建模,对所提减淤措施的可行性、合理性和适用性进行了探讨和研究,总结了类似水闸工程引河淤积的共性规律和减淤途径,可为工程日常管理提供指导。The siltation of the lower reaches of Liuduo South Sluice has become more and more serious in recent years.It has not fundamentally alleviated the current situation of channel siltation although it has been dredged for several times.Three kinds of siltation reduction measures are put forward based on the analysis of the causes of the siltation in the lower reaches of Liuduo South Sluice,namely dam construction at the entrance to the sea,reasonable opening and discharge of the sluice as well as gate site downward movement.The feasibility,rationality and applicability of the proposed siltation reduction measures are discussed and studied by using the theory of hydrodynamics,water and sediment movement,which are supplemented by numerical modeling,and the common laws of the siltation in the diversion of similar sluice projects are summarized and the method to reduce siltation are summarized,thereby guiding daily management of the project.
