海岛堤坝修复对海滩稳定性的影响研究

摘要

On the basis of field survey, the characteristics of seas waves and the situation of tidal current field in Da Lu Island surrounding area were simulated by using numerical simulation method, meanwhile the paper discusses the sediment movement and terrain changes which caused by waves and tidal current field, then get the wave factors of project design, thereby analyzes the effects of the breakwater repair on the beach stability of DaLu Island. The results show that the impacts of the breakwater repair on the waves and tidal current field are little;under the overall action of the waves and tide, the construction of the project will not make South beach erosive.%本文在现场调查的基础上利用数值模拟方法模拟了辽宁大鹿岛周边海域波浪分布特征及潮流场情况，探讨了波浪和潮流流场可能引起的泥沙运动和地形变化情况，进而得到了可供工程设计的波浪要素，据此分析了大鹿岛防浪堤修复对周边海滩稳定性的影响。结果表明：防浪堤的整治与修复对前部水域波浪于潮流流场影响微小；在波、流综合作用条件下，工程的建设不会使南侧的海滩产生较明显的蚀淤变化。
