摘要
管跨的涡激振动是引发管跨发生疲劳失效的主要因素之一 ,也是管跨可靠性设计、可靠性评估工作所要解决的主要问题。针对由涡激振动引发的海底管跨的疲劳失效 ,利于随机过程理论和可靠性分析理论 。
The vortex induced vibration of pipeline span is the leading factor of fatigue invalidation of pipeline, and is the most important confronted and urgent to be solved problem during the reliability design and evaluation of pipeline span. Concerning fatigue invalidation of pipeline span caused by vortex induced vibration,a reliability analysis method being more corresponded to the operation status of pipelines is presented based on stochastic processes theory and reliability analysis theory.
