莱州湾东岸沿岸输沙率及冲淤演化动态分析

The Calculation of Alongshore Silt Discharge Rates and Evolution Development in the Eastcoast of Laizhou Bay

采用美国《海岸防护手册》的CERC公式对莱州湾东岸的沿岸输沙率进行计算;同时根据莱州湾东岸自身特征,采用岬间海湾平面平衡形态经验模型-抛物线模型对莱州湾东岸的平衡状态进行预测,结合两者分析得出莱州湾东岸的冲淤演化动态:屺姆岛南侧西端略有冲刷;龙口湾顶基本无泥沙进出;招远岸段遭受严重的侵蚀;石虎咀处于淤积状态。针对侵蚀岸段提出了防止海岸蚀退的对策。

This crtiele uses CERC formula of the United States 《protection manual in coast》to calculate the silt discharge rate. According to the Longkou Bay characters. The equilibrium appearance experience modelparabola model is used to predict analysis the East coast of LaiZhou Bay revolution development. The results show that the west of the south side of Qimu island have already flush slightly, the bay crest didn＇t lose or get sand, Zhaoyuan shore segment is suffering serious erosion and the Shihu sand mouth appearance is silt upo Give the reasonable advice according to the erosion parts.
