摘要
内孤立波是由内潮在特殊地形条件下所激发的存在于密度跃层中的大振幅波动。在其传播过程中产生的扰动可导致海水强烈辐聚和引发突发性强流，对海洋工程、石油钻井平台和海底管道会造成严重的威胁。为充分了解南海北部内孤立波，利用南海北部流花海区一套潜标系统实测数据，对该区域的内孤立波振幅、流速、时间等特征进行了研究，并对内孤立波引起的剪切流进行了分析。研究成果可为南海海洋油气工程建设和施工作业提供参考和技术保障。
Internal solitons with large amplitude are internal tides excited by the interaction between barotropic tides and bottom topography of the ocean, and will have great impacts on the safety of ocean engineering, oil drilling platforms and submarine pipelines. According to the observed data from a submerged buoy system at Liuhua area in northern South China Sea （SCS）, characteristics of internal solitons, such as amplitude, current speed, duration, and shear velocity are studied in this paper. The results can provide a reference and technical support for the design and construction in SCS.
