人工岛是一种新兴的海洋工程, 在海湾中进行人工岛建设引起的岸滩淤积和冲刷问题已日益得到人们的关注。以海口湾南海明珠人工岛为例, 通过数值计算和类比的方法, 分析了人工岛建设对海口湾西海岸岸滩稳定性影响, 并提出了相应的防护措施。相关研究和工程实例表明, 在海湾中填海建设人工岛后, 通常会造成人工岛所对应岸滩形成向海突出的舌状岸线, 而其两侧会出现海岸侵蚀。对于冲刷部分, 可采取海滩补沙等工程措施加以控制或恢复。

Man-made island is a new form of ocean engineering. Great attention has been paid to the problem of depositing and eroding caused by such construction. By computing and analogy, we analyzed the effect to stability of the beach in the west coast of Haikou Bay due to the construction of a man-made island using an example of south-sea-bright-pearl man-made island, and proposed some protection measures. The related study and engineering cases indicated that the opposite beach would universally form prominent shoreline like a tongue, but the two side beaches would erode. We should take some engineering measures, such as supplying sand to the beach, to control and recover the eroded beach.
