摘要
根据北戴河西海滩人工养滩后实际监测数据,对养滩工程中潜堤岬头的养滩功效进行分析,并通过数值模拟的方法进行验证。结果表明,潜堤岬头起到了很好的消浪促淤效果。岬头建成后,沙滩整体以淤积为主,局部岸段发生侵蚀,但侵蚀量不大,低潮滩以上沙滩平均单宽淤积量为21.3 m^3/m,其中,M4剖面单宽淤积量最大,为98.3m^3/m;数值模拟结果肯定了岬头的消波减能功效,其预测的岸线形态与实测岸线基本一致。
According to the actual monitoring data of the after West Beach artificial nourishment,Beidaihe,the artificial nourishment efficacy of the submerged headland was analyzed.At the same time, this efficacy was validated by numerical simulation.The results showed that the submerged headland played a good role in weakening the wave energy and promoting the sedimentation.After the completion of submerged headland,the whole beach showed siltation state,and only in the local beach for the erosion state which was very small.Average single width deposition volume of the beach above the low tide beach was 21.3m^3/m.The maximum single width deposition volume occurred in the M4 profile section,and its was 98.3m^3/m.Numerical simulation results confirmed the efficacy of the submerged headland to weakening the wave energy.Its predicted shoreline pattern was basically the same as the measured shoreline.
