飞雁滩油田海域刁口河岸滩侵蚀演变规律分析

Analysis on erosion evolution of the Diaokou River's coastal of the Feiyantan oilfield sea area

为了探讨飞雁滩油田海域刁口河岸滩水下三角洲的侵蚀演变规律,根据该海域多年实测水深数据,采用Surfer软件对海岸冲淤总体变化进行了直观分析。应用Origin软件完成了CS3～CS7 5个剖面的水深对比图,通过该图分析了不同年份同一剖面的变化及累计蚀淤深度情况,分析了侵蚀演变的原因及规律,为海岸侵蚀治理与防护提供了理论依据。

In order to discuss the erosion evolution rule of subaqueous delta in the Diaokou River＇s coastalof the Feiyantan oilfield sea area. In this paper, analysis on the overall changes in coastal erosion anddeposition is performed by using software-Surfer, and the analysis data are many years＇ measured waterdepth data in this sea area. Water depth comparison diagrams of five profiles-CS3～CS7 were completed by using software-Origin, from this diagram, we analysed the change and accumulative depth of erosion and sedimentation of the same profile in different years, and analysed the causes and rules of erosion evolution, and can provide a theoretical basis for coastal erosion management and protection.
