依据以往多次东海海底管道检测成果资料, 分析和探讨了形成海流冲刷作用的各种因素, 可以归结为内部海洋环境和外部环境变化两大因素, 以及这些因素可能对海底管道产生危害影响的程度, 并总结了在长期的海流冲刷作用下海管的空间状态、海底受冲蚀的表现形式和海床冲淤变化, 提出了今后检测和维护工作的一些建议。

On the basis of previous submarine pipeline survey results many times in the East China Sea, this article analyses and discusses the varied factors of cause current scour action, which can be divided into two major factors of the internal marine environment and the external environment change, and probably harm to the pipeline, and sums up the space condition of the pipeline, the sea floor form and the sea-bed erosion and deposition changes under the long-term current erosive, put forward some suggestions to inspection and maintenance of submarine pipeline.
