| 摘 要： | 基于线性和非线性波浪理论，在渤海海域观测的30种海况下，选取了导管架平台易发生疲劳损伤的几个危险节点作为研究对象，并通过确定性的疲劳分析方法对这些节点进行了疲劳寿命评估。结果表明，在选取的3种阻尼条件下，考虑波浪的非线性因素后，疲劳寿命的评估结果均有所增加，为海工结构的疲劳寿命评估提供了参考意见。

| Abstract: | Based on the linear and nonlinear wave theories, on the 30 types of observed sea conditions in Bohai sea , several dangerous nodes which are easy to have fatigue damage on jacket platform were selected as objects of study, and fatigue life assessment of these nodes were conducted by the method of deterministic fatigue analysis. Results indicate that after considering the nonlinearity of wave, the results of fatigue life assessment has increased under the selected condition of three kinds of damping. This paper provided reference opinions to the fatigue life assessment of offshore structure. |
