摘要
水流、泥沙一直是建港中关键问题之一。从现场水文泥沙条件分析和数学模型计算等方面,分析比选了洋山港规划方案,提出了洋山港总体规划以单通道方案为宜,不但能简化现场的复杂的水流,选择合适的口门宽度还能维持深槽水流、水深条件,经计算分析提出了西口门宽度为3.5km的规划方案较好,此外还从平衡水深的角度对单通道方案的维持水深进行了计算。
Current dynamics and sediment conditions are always one of the crucial problems in harbor layout. According to the analysis on the current velocity, sediment content in past surveys and the results of numerical modeling for the general layout of Yangshan harbor, it is suggested that the single-channel option should be optimized in the plan, not only simplifing the complicated current structure, and also keeping the current dynamic condition and water depth in the deep trough when a suitable width of the west gate are selected. 3.5 km for the width of the west gate are adoptable. Further more, the study gives a simple estimation for the water depth after the single-channel option is built according to the river bed equilibrium formula.
