摘　　要：随着海洋石油开发的快速发展,大量的海底管道被安装并投入运行。针对海底管道常见的淘空现象,采用染色液流场显示方法,试验研究海底管道从部分裸露到完全裸露后其周围流场的特征,揭示了海底管道淘空过程。With the rapid development of the ocean petroleum industry,a lot of submarine pipelines have been installed and put into action.In this paper,the flow characteristics around a submarine pipeline was studied from the pipe exposing partly to its scouring fully and the scouring process was investigated by flow visualization according to the scoring status of the submarine pipelines.

关 键 词：海底管道 流场 淘空
