关于为起床人的地震设计的标准都不可得到、相关,是众所周知的研究没被报导。起床人动力学的全面研究在这篇论文在地震期间被执行。为起床人的地震分析的一个动态模型根据起床人的工作环境和管道的惯性力量的影响被开发。为发达模型的动态方程根据横梁的精力理论被导出并且解决。为 Bohai 油领域里的一个设计工程的数字模拟,中国证明起床人的基本频率在地震回答起主要作用,并且为在 Bohai 的浅水里的平台海湾,起床人由于起床人频率和地震波浪频率之间的突出的差别表明低得多的压力回答。为地震分析的介绍模型和它的相应方法为对地震波浪抵抗的起床人设计实际、重要。
It is well known that no criterion about seismic design for risers is available, and relevant research has not been reported. A comprehensive study of riser dynamics during earthquakes is performed in this paper. A dynamic model for seismic analysis of risers is developed in accordance with the working environment of the risers and the influence of inertia force of the pipelines. The dynamic equations for the developed model are derived and resolved on the basis of the energy theory of beams. Numerical simulation for an engineering project in the Bohai Oil Field, China shows that the fundamental frequency of the riser plays the major role in the seismic responses, and for platforms in shallow water in Bohai Bay, the risers demonstrate a much lower stress response due to prominent differences between the riser frequency and the earthquake wave frequency. The presented model and its corresponding method for seismic analysis are practical and important for riser design resistant to earthquake waves.
