天津港回淤现状与回淤规律研究

Study on Silting Status and Patterns of Tianjin Port

根据天津港 1 994～ 1 998年实际维护疏浚工程参数的测定与分析 ,对全港的回淤状况有了充分认识 ,在此基础上 ,综合分析研究港域水文泥沙条件与回淤泥沙特性及影响回淤的主要因素 ,得出天津港现状下港池、航道泥沙、回淤强度分布计算式 ,并与实测资料进行了比较 。

On the basis of full understanding of silting status of Tianjin Port from determination and analysis of the parameters of practical maintenance dredging of the port from 1994 to 1998, hydrologic sediment conditions, silting sediment features and the main factors influencing the siltation are studied. Therefore, the formulas of distribution of silting strength in the basins and channels are obtained. And through comparison, it's shown that the calculated result is in good agreement with the measured data.
