| 摘 要： | 本文研究了海洋平台结构系统疲劳可靠性评估方法。文中对平台结构简生管节点疲劳可靠性分析模型进行了简单的评述，在该模型的基础上，建立了用S－N曲线模型与断裂力学模型分别计算平台完好管节点及有初始裂纹管节点疲劳寿命的平告结构系统疲劳可靠性分析模型。作为一个算例，文中运用作者开发的程序系统，对一固定式导管架平台进行了疲劳可靠性计算。

| Abstract: | The fatigue reliability evaluation method for the off shore platform structural system is studied in this paper. The fatigue reliability analysis models for off shore platform structural simple tubular joint is simply discussed. Based on fatigue reliability analysis model for simple tubular joint, fatigue reliability analysis models that S-N cruve and fracture mechanics models are used to calcu1ate fatigue lifes of complete tubular joints and initial crack tubular joints for platform structural system are established. As an example, by using the computer program that is designed by the authors, the fatigue reliability analysis is given for a Bohai fixed jacket platform. |
