【摘要】 浅埋海底管线由于外部环境荷载的改变,必然引起一定的附加应力。在这种条件下,必须对管线采取防护措施。提出了浅埋海底管线的防护方案,并应用有限元方法,建立了同时考虑土体-结构-海底管线三者耦合作用的二维有限元分析模型,对采取保护措施的海底管线进行应力的分析计算,计算结果表明所采用的防护方案是合理的。更多还原

【Abstract】 Shallow buried seabed pipeline can be subjected to subsidiary stress as a result of the load fluctuation. In this paper, a protection method is recommended and a finite element method is used to implement the stress analysis on seabed pipelines under protection. The interaction between the structure, soil and pipeline is considered in the modeling. The analysis results could prove the rationality of the protection scheme.更多还原
