摘要

摘要: 为研究老虎石海滩养护工程对老虎石浴场及周围岬湾的水动力环境的影响,利用MIKE 21建立工程区海域二维潮流数学模型,通过实测流速、流向对模型进行验证,将验证后模型参数运用到工程设计方案下潮流场的模拟,比较分析工程前后水动力环境的变化。潮流场比较结果表明,修建潜坝会使得工程及其附近的潮流场发生小幅变化,但对该海域整体的潮流动力环境影响甚微。工程后老虎石海域的潮流动力仍然很弱,对保存海滩上人工养护的泥沙是非常有利的。

Abstract: A beach nourishment project will be conducted at the Laohushi beach of Qinhuangdao. To better understand the impact of the project to the tidal field, a 2D tidal field model was setup based on MIKE21 model. The model was verified by comparison of the simulated and measured data of tidal level, velocity and direction. The verified model is adopted to simulate the tidal fields after the project with the same computational parameters and open boundary conditions. The comparison of the tidal flow before and after the project shows that the impact of the sandbars to the tidal current is limited in the region around the sandbars, and negligible in the region 500 m far from them. The tidal current in the Laohushi beach after the project is still very weak to move the sands away from the beach.
