海底长输油气管道的隆起屈曲分析

Upheaval Buckling Analysis of Long Offshore Multiphase Pipeline

该文基于Palmer等研究学者提出的半经验解析公式,探讨了海床几何初始缺陷、温降及土壤特性等因素对分析结果的敏感性。结合工程计算所需的前提假设,通过使用自编程序对一工程实例进行分析,结果表明该方法的计算量小、直观性强,对工程设计具有一定的指导意义。

Based on the semi-analytical formulation proposed by Palmer et al, the sensitivity of analysis results influenced by geometry imperfection, temperature decreasing and soil parameter were investigated. Combined with the assumption required in the practical project, an example will be analysed by in-house program, which can direct the engineering application.
