摘要
研究地震海啸行移时通过海底悬跨管段区域时对管道的影响。假设悬跨段两端不受地震海啸影响,因为海啸为长波,本文根据传统Morison方程计算了海底悬跨管道在行移的海啸波浪荷载作用下的受力情况,并应用有限元软件ADINA进行了建模分析,通过模拟结果分析海啸波浪对海底悬跨管道受力的影响并判断是否会对海底管道造成破坏性影响。
Currently the mechanical analysis of spanning submarine pipelines has been an important research topic in the development of marine resources.In this paper,research is the impact of the pipeline when the tsunami shift through theregion spanning submarine pipelines.Assuming both ends of the suspended pipe from the impact of the earthquake and tsunami and the tsunami wave is long-wave,based on the traditional Morison equation,calculated the force of de spanning submarine pipelines when the tsunami wave moving through it,modeling and analysis it with the finite element software ADINA.Determine the devastating effect whether worked on the submarine pipelines by analysis the results of simulation for the tsunami waves walk through the spanning submarine pipelines.
