摘　　要：海底管道常埋置于海床以下一定深度,海床冲刷可能会影响海底管道的运营安全。针对册镇海底输油管道建成以后沿线海床冲刷现象,利用实测资料分析海床冲刷特征,并结合周边工程建设情况分析冲刷原因。研究表明:册镇海底输油管道沿线海床冲刷主要集中在两个区域,分别位于管道镇海登陆段和管道弯顶段。其中,镇海登陆段的冲刷与新泓口围垦工程有关,目前已趋于稳定;而管道弯顶段的冲刷主要由金塘大桥桥墩阻水导致水道间水动力变化而引起,目前仍处于发展中。Since the submarine pipelines are often deeply buried in the bottom, the scouring and silting evolution of seabed has a significant influence on the stability of pipelines. By using the measured data and combining the situation of peripheral engineering construction, the characteristics of seabed scouring are analyzed and the causes of erosion are studied in this article. The research shows that there are two main seabed scouring areas along the submarine pipelines, one is the landing position in Zhenhai, the other is the bend area of pipelines. The seabed scouring of the landing position in Zhenhai is related to the Xinhongkou reclamation project and now is settle out; the reasons of seabed scouring in other places are caused by water power setting changes in Jintang bridge, the seabed scouring is in the state of development.
