| 摘 要： | 根据波能流法,采用SMB公式、徐啸公式和夏都公式对大连长兴岛海域的沿岸输沙率进行了定量计算,并从泥沙来源、海岸地形与地貌方面,对海域的沿岸输沙问题进行了定性分析。综合定量计算与定性分析的结果,长兴岛海域沿岸输沙属于微弱型,对港口建设无大碍。

| Abstract: | According to the wave energy flux method,longshore sediment transport rate of the Changxing Island sea area of Dalian is quantitatively calculated with SMB formula,Xu Xiao formula and Chatou formula.Furthermore,from such aspects as sediment source,coast landform and morphology, longshore sediment transport in the sea area is qualitatively analyzed.The synthetical analysis of the quantitative and qualitative results indicates that longshore sediment transport rate in the sea area is weak and will not creat serious effect on construction of harbor. |
