摘要：

根据断面水文测验结果,分析确定了海区底质泥沙特性,海水含沙量及流速;对闸下港区造成泥沙淤积的原因进行了较深入的分析;根据水文测验的有关数据,运用一般“文献方法”和“规范方法”分别对港区泥沙淤积强度作了估算;对于如何冲淤和减淤,从方法上和理论上作了论述。

Based on the results of sectional hydrologic survey and measurements,the properties of the sediment load,sediment concentration in the seawater and the flow rate of seawater in the sea area are analyzed and ascertained and the causes of siltation in the downstream port area from the ship lock are analyzed in greater depth.The density of siltation in the port area is estimated separately with the common Method in Literatures and Method in Specifications on the basis of the relevant hydrologic testing data.It is also methodologically and theoretically expounded how to sluice away the silt and to reduce siltation.
