摘要/Abstract

摘要： 本文基于历年检测资料统计分析了杭州湾海底输油管道裸露埋深状态变化规律,结合水文地形测量资料、辅以数学模型手段,从Spoiler自埋设计、杭州湾水流特性、管道路由海床演变特性以及人类活动等多因素探索了杭州湾海底管道裸露埋深状态变化的原因。研究结果表明:杭州湾管道80%以上处于埋深状态,局部管段长期裸露,裸露管段主要位于北岸深槽和庵东边滩滩坡区域;管道冲刷与管道路由海床演变特性、水流与管道夹角以及Spoiler自埋设计的发挥密不可分;杭州湾南岸围垦工程的实施与该区域管道裸露、掩埋状态密切相关。

Abstract: The variation regularity of submarine pipeline's status in Hangzhou Bay was analyzed based on inspecting data over years. The variational reasons of pipeline's exposed and buried status were explored based on the hydrodynamic numerical model and the integrated factors such as the self-burying design of Spoiler, the flow characteristics and the seabed evolution, the human activities in Hangzhou Bay and so on. The results show that above 80% of the pipelines are buried under seabed,while some parts of pipeline are chronically unburied, and the unburied pipelines are mainly located in the deep groove of north shore and the frontier of Andong Beach. The pipeline's scouring is close related to the seabed variational characteristics, the angle between the flow and pipeline, and the self-burying design of Spoiler. In addition, the reclamation project in the south beach of Hangzhou Bay may play an important rule for the pipeline's exposed and buried status.
