摘　　要：给出了动冰力作用下海洋石油平台振动可靠性的分析方法 ,建立起避开共振和限制振动响应两类可靠性模型 ,为定量评估平台冰激振动的可靠性创造了条件。通过实例分析 ,得出一些有益的结论 。The method to analyze the reliability of offshore platform vibration caused by ice excitation force is given first and then two types of reliability models are established respectively to avoid covibration and to restrict vibrational response, thus providing conditions for a quantitative assessment of the reliability of ice-excited vibratioin of offshore platform.Some conclusions are drawn from case study,which may be helpful in practical application.
