摘　　要：本文研究了海上导管架平台的管节点柔性模拟方法,分析其对结构内力及位移的影响,及其导致的不同构件刚度和强度变化。通过南海西部典型导管架平台的分析,分别对比3种理论的差别;与刚性假定的结果对比,总结出节点柔性技术对结构强度、疲劳寿命以及极限强度的影响的一般结论。This paper studies the joint flexibility on offshore jacket platform,to figure out its effect on structure internal forces and deflection,which results in changes of stiffness and strength of members.By application of three classic joint flexibility theory and rigid theory on typical jacket platform in the South China Sea,the result of structural strength,fatigue life and ultimate strength have been compared.It comes to the general conclusion on influences of tubular joint flexibility on jacket structure.

关 键 词：导管架平台 管节点 柔性 冲剪 极限强度
