黄河三角洲桩西至黄河海港海域冲淤演化特征研究

Study on changes in scour and silting of submarine topography in the Yellow River Delta from Zhuangxi to the Yellow River port

针对目前胜利油田海堤防护工程有27.7 km 的临海海堤存在非常严重的安全隐患,根据历史资料分析、数值模拟以及实测资料推算,研究了黄河三角洲地区桩西至黄河海港海域25 a,50 a 一遇渡流共同作用下冲淤变化,得出研究区海域冲淤演化特征。为该海岸段海岸防护工程加固方案的设计、施工以及工程的灾害预测,提供了可借鉴的科学依据。

At present, the defendable projects builed by ShengLi oil field long 27.7 km are in danger, according to a historical material analysis, Numerical model and measured datum calculation, aimed at investigating the changing rules of scouring and filling in the case of once-in-50-years wave and current from Zhuangxi to Yellow River Port, obtained the evolving characters of scouring and filling ,and provided a scientific support for coastal engineerings.
