| 摘 要： | 针对秦皇岛洋河口至戴河口海岸整治工程,采用数值模拟方法研究该区域潮流和波浪对人工岛及海岸整治工程的响应特征,发现人工岛与海岸整治工程共同存在时对潮流的影响并非二者单独作用的线性叠加,而是存在着非线性的关系,而常浪对人工岛和海岸整治工程的响应基本上为对二者单独作用响应的线性叠加.同时建立海岸整治工程时预留潮汐通道有助于保证工程海域的水体交换,减小对周边环境的影响.这些结果对相似海岸动力的海滩整治工程可提供科学参考.

| Abstract: | Based on the beach nourishment project between the Yanghe Estuary and the Daihe Estuary, the numerical simulation method is adopted to study wave-current coupled hydrodynamic responses to artificial island and beach nourishment projects. It can be found that changes in tidal current caused by the combination of artificial island and beach nourishment projects are not linear superposition of differences induced by artificial island project and beach nourishment project respectively, however, the changes in wave field have a linear superposition relationship. Reserving tidal channel in beach nourishment project is necessary for good water exchange, which benefits alleviating its influence to surrounding environment. The findings can provide a reference for beach nourishment under similar conditions. |
