摘要
根据水槽概化模型试验现象和结果，分析了盲肠式港渠口门回流的淤积特性，包括淤积模式、淤积形态、淤积物级配分选以及河床变形特点等。讨论了影响回流淤积的主要因素，建立了回流淤积率的估算公式，并对防止泥沙淤积的工程措施作了初步探讨。
In this paper, based on the exprimental results of a testing flume model, a systematical study on sediment deposition caused by circulating flow in the cecum branch is made. Details on the model of deposition, the size of infiunce zone, the variation in size distribution of sediment depositions and the properties of riverbed deformed are discussed. The main factors which influence the sediment deposits are analysed, and a formula to estimate the sediment deposition rate in the closed channel is also established. Finally, a project measure for control sediment deposits is presented.
