摘要
海底管线的管跨在稳定海流的作用下，可能发生涡旋激振。石油大学（北京）海洋石油工程研究室受中国海洋石油总公司的委托，设计了模型实验，以研究管跨涡激振动的规律。文中介绍了该实验研究的概况，并对实验数据进行了分析。其结果表明，管跨的同向涡激振动一般不会对管线系统的正常运行构成威胁。
Abstract If the submarine pipeline is exposed to wave or current forces,the unsupported pipe may be susceptible to flow induced vibration which could adversely affect its safety.Research Center of Offshore Oil Engneering of University of Petroleum,China,urged by China National Offshore Oil Corporation,designed model tests to study the beha viors of such line pipe spans in a steady current.The results show that in line vibration can not bring serious danger to submarine pipeline system in most cases,while cross flow vibration must be eliminated.
