摘要
本文回顾了渤海平台的冰振历史,平台结构特征和自振频率;分析了渤海海冰特征,现场试验和实验室试验结果及计算机模拟结果;给出了抗冰振的理想构件——寄生在潮差段的正倒锥组合体。
This paper reviews the ice vibration history ,structural features and self-oscillation frequancy of platforms in Bohai Sea;analyses the characteristics of ice in Bohai Sea,the results both from on -the -spot and laboratory experiments and the computer simulation results ;proposes the ideal anti-vibration member against sea ice-the combination of right and inverted cones attatched on the splash zone of pile.
