| 摘 要： | 通过对平台在风浪作用下的振动测试分析，发现了直立式非灌浆桩腿导管架平台在海底冲刷条件下发生异常振动的原因是导管架与桩之间存在较大的相对运动，以至于在风浪较大时发生碰撞。因而，结构的动力特性和动态响应都与设计结果不一致。在非极值海况条件下，平台的振动超出了设计预测值，并提出了治理和设计建议。

| Abstract: | It has been shown that the excessive vibration of a jacket platform with non-grouted vertical piles is due to the relative movement and the impact of the jacket and the piles under the condition of scouring. Therefore, the dynamic characteristics and the response of the platforms are not expected by the designers. The vibration of the platform is abnormal under non-extreme ocean environment. Also, a scheme of mitigating its vibration and a proposal for designers have been forwarded. |
