| 摘 要： | 埕岛油田主要分布粉土和淤泥质软土2类典型的海床.通过建立海床与其上裸置管线相互作用的有限元计算模型,对埕岛油田2类典型海床上裸置管线的在位稳定性进行了数值计算分析,并与现行常用的DNV(挪威船级社)管道设计方法的计算结果进行了对比.分析表明,对于埕岛油田粉土海床上裸置管线的在位稳定性分析,数值计算结果与DNV简化分析方法的结果较为一致;对于埕岛油田淤泥质软土海床上裸置管线的在位稳定性分析,DNV简化分析得到的裸置管线的在位稳定性一般高于相应的数值计算结果.

| Abstract: | In Chengdao oil field,there are two main kinds of typical seabed,that is the silt seabed and the soft-clay seabed.Based on the finite element model for interaction of the seabed and the untrenched submarine pipelines,on-bottom stability analysis of submarine pipelines on the two kinds of typical seabed has been performed.The numerical results have been compared with that of the DNV pipeline stability design standard.The comparison has shown that for on-bottom stability analysis of submarine pipelines on the... |
