| 摘 要： | 桶形基础平台是一种新型的海洋结构,由于目前对该结构的研究集中在桶基失效及承载力方面,其抗冰振性能还很模糊。文章基于对渤海单立柱式桶基平台的多年现场监测,发现其冰振加速度响应显著,明显高于导管架平台结构。利用谱分析方法对一实际桶基平台进行了冰振疲劳寿命分析,计算结果表明,关键点疲劳寿命符合规范要求。最后,提出此类结构冰振抑制策略,为其结构抗冰设计提供依据。

| Abstract: | The bucket foundation platform is a new foundation pattern in ocean engineering.Until now,the most research is focus on failure analysis and reaction force of the bucket foundation,but the structural ice-resistant performances are not well developed.In this paper,combined with the field monitored data of some bucket foundation platforms in Bohai Bay,ice-induced vibrations are analyzed.The results show that even though these structures may effectively resist extreme static ice forces,the ice-induced accelera... |
