摘要
针对在粉砂淤泥质海岸实施牡蛎礁修复时极易受波浪作用产生倾覆的问题,根据人造牡蛎礁不同的施工布置方式进行分类,并针对每种类型人造牡蛎礁提出对应的波浪稳定性评估方法。以舟山市六横大岙盐沼修复及海堤生态化建设工程的牡蛎礁修复方案为示范应用,利用波浪物理模型开展不同潮位、不同波浪和不同类型牡蛎礁的波浪试验研究,根据试验结果并结合人造牡蛎礁稳定性评估方法,评估各种类型人造牡蛎礁体的稳定性。研究结果表明:提出的人造牡蛎礁波浪稳定性评估方法能够对不同类型礁体给出针对性评估指标,评估结果合理可靠;破碎波作用下人造牡蛎礁波浪力受力较复杂,建议通过物理模型试验测定。研究成果可为人造牡蛎礁布置位置和结构设计提供技术支撑。
This study aims at the problem that oyster reefs restoration is prone to overturning due to wave action on the silty and muddy coasts.Classification is made according to different construction layout modes of artificial oyster reef,and respective wave stability assessment methods are proposed for each type of artificial oyster reef.Taking the restoration scheme of oyster reef of Liuheng Da’ao Salt Marsh Restoration Project and Seawall Ecological Construction in Zhoushan as example,wave physical models were carried out to evaluate the stability of different types of artificial oyster reef on the conditions of different water levels,waves and types of oyster reef.The research results show that the wave stability assessment method proposed can provide reasonable and reliable targeted assessment indicators for different types of reefs.Due to the complex wave force on artificial oyster reef under the action of breaking wave,it is suggested to measure the stability through physical model tests.The research results can provide technical support for the layout and structural design of artificial oyster reefs.
