神华黄骅港外航道泥沙淤积问题总结与探讨

摘要

Hydrodynamic force and sediment environment of the Huanghua sea area were analyzed. Based on observation data and research results, the mechanism of sediment transport and channel siltation and the sediment sources in the outer channel of Huanghua Port were expatiated. The three sediment sources of strong siltation were proposed in Huanghua Port channel, including the transit sediment around the shallow waters, the beach face sedi-ment near bilateral channel and the dredging residual silt. The proportion and the changes of back-silting in Huang-hua Port channel were also analyzed.%对黄骅港海区的水动力泥沙环境等自然条件进行分析，基于黄骅港航道十多年的现场观测资料和近几年的研究成果，对外航道泥沙运移形态、回淤机理和回淤泥沙来源等问题进行论述和探讨。提出了黄骅港航道回淤的3种泥沙来源，即近岸浅滩中转泥沙、航道两侧滩面泥沙、疏浚废弃泥沙，并分析了在回淤中所占的比例及其变化。
