莱州港二号港池及5万吨级航道工程二维潮流数学模型研究

2-D tidal current numerical model of harbor basin No.2 and 50000 dwt waterway engineering project of Laizhou Port

根据实测资料分析,莱州港海区浪小、流小、含沙量小、泥沙来源少,具有建设5万t级码头的良好自然条件。运用数学模型的方法,建立了莱州港2号港池及5万t级航道工程前后的二维潮流数学模型。计算结果表明,新规划港区航道建成后,整体潮流场变化不大,对海区整体潮流影响甚微,但口门处的回流将影响口门淤积。

Based on the measured data, there pended sediment concentration and little sediment possess nice natural conditions with small wave, little flow, low sussource at sea-areas for 50 000 dwt waterway construction in Laizhou Port. According to the data, a 2-D numerical model of 50 000 dwt waterway engineering project was established. The study results are as follows：The whole tidal flow field changes little after the waterway construction, and the project has a little effect on the whole tidal current of sea area. The circunffluence at the entrance will affect the deposition there.
