摘要
在利用潮流数学模型对连云港港徐圩港区防波堤工程方案进行比选优化时,发现港区内涨潮最大流速是决定方案能否成立的关键指标之一。经过分析认为,港区内涨潮最大流速与港区水域面积、防波堤口门过水断面面积有关,此外还受涨潮潮差和涨潮历时的影响。根据潮流数学模型的计算结果,拟合了港区内涨潮最大流速计算的经验公式,相关性较好,计算精度较高,可以用于徐圩港区防波堤工程方案的初步评估。
In the use of a tidal mathematical model to optimize the layout of the encircled breakwater in Xuwei port, the maximal velocity in the port area is considered as a very important index. It is found through analysis that the maximum velocity is related to the waterside area, the flow section area of port entrance, and the tidal range and last of flood tide. According to the simulation results of the mathematical model, we develop an empirical formula to calculate the maximum velocity, which can be used to estimate the design plan in preliminary evaluation.
