摘　　要：在温度和压力荷载作用下,裸置海洋管道产生的高压缩轴向力容易引发管道的侧向屈曲,造成管道结构失效破坏。针对裸置海洋管道侧向屈曲可能性评估问题,研究了管道侧向屈曲分析中重要的管-土相互作用评估方法,分析了Hobbs(1984)管道侧向屈曲分析理论,并结合工程算例总结了裸置海洋管道侧向屈曲可能性的评估计算方法,结果可为实际工程项目提供参考。The high compressive axial force generated by the exposed offshore pipeline under the action of temperature and pressure load can easily cause the lateral buckling of the pipelines,resulting in the failure of the pipeline structure.Aiming at possibility assessment problem of lateral buckling of exposed offshore pipeline,the evaluation method of pipe-soil interaction,which is very important in the lateral buckling analysis,was presented.The lateral buckling analysis theory of Hobbs(1984)pipeline was analyzed.The evaluation calculation method of lateral buckling possibility of exposed offshore pipeline was summarized by combining with engineering examples,the results can offer reference for practical engineering projects.
