东营港水动力要素及泥沙运动特性

Hydrodynamic factors and sediment movement characteristics in Dongying Harbor

收集整理了东营港现场波浪、潮汐、潮流及泥沙底质等实测资料,分析得到该海域波浪动力以东北向和西北向为主,潮汐类型为正规全日潮,潮流特性表现为基本平行于海岸的往复流,流速较大,海域底质以黏土质粉砂为主,属于粉砂质海岸类型。在此基础上,根据刘家驹波浪作用下泥沙起动公式,计算了港口附近海岸泥沙在不同水深下起动波高与泥沙粒径的关系,为东营港港区规划及相关研究提供参考依据。

Based on collection and arrangement of wave,tide,current and sediment measured data in Dongying Harbor,we have studied that the wave is dominated by northeast and northwest direction,the tidal type is regular diurnal and featured by reciprocating current parallel to the coast,the sea bed of the sea area is mainly composed of silty clay,which belongs to the sandy coast type.According to the formula of sediment incipient motion under wave created by LIU Jiaju,we calculated the relationship between sediment incipient wave height and the sediment grain size in different water depth near the harbor,which provides a reference for port planning and related research in Dongying Harbor.
