摘要
使用有限元法确定了管土作用中粘土海床对于管道的侧向等效摩擦系数,透过该摩擦系数分析了管土作用对于SCR立管疲劳破坏的影响。结果表明管土作用对于SCR立管疲劳破坏具有较大影响,这种影响主要集中在SCR立管着地点附近。
Equivalent lateral friction coefficient between pipe and clay in pipe-soil interaction process is calculated using finite element method, and then effect of pipe-soil interaction on SCR's fatigue damage is estimated based on this coefficient. Studies in this paper show that the interaction between soil and pipe has obvious influence on SCR's fatigue damage, which mainly concentrates on the part near the touch-down point of SCR.
