摘　　要：该文指出导管架平台结构延寿的迫切性和基于传统分析方法结果下检测规划的缺陷,并将RBI技术引入平台延寿的检测规划中。文中给出了导管架RBI(基于风险的检测)技术原理、疲劳失效概率分析方法、平台倒塌概率分析方法和导管架RBI分析流程,并通过具体工程算例,得出RBI技术有利于控制风险和减少检测成本的结论,为在役导管架平台结构的完整性管理提供了良好的借鉴。This paper points out the urgency of jacket platform structure＇s life-extension and the faultiness of inspection plan based on the traditional analysis method＇s results, intro- duces RBI（risk-based inspection） technique into the inspection plan for life-extension. The jacket RBI technical principle, fatigue probability analysis method, platform collapse probabil- ity analysis method, jacket RBI analysis process and engineering sample are given, and draw the conclusion that RBI technique is more beneficial to control the risk and reduce cost of in- spection. It will provide a good reference for integrity management of in-service jacket plat- form structure.
