摘要 叙述损伤识别技术——在线监测技术的原理,以5种不同构造形式的简化导管架平台和北海Claymore CPP导管架平台为例,计算平台考虑初始缺陷和附加水质量后的固有频率,并对平台整体进行非线性倒塌分析以获得结构的极限承载力,以及构件失效对平台极限承载力的影响,旨在检验在线监测技术对于四腿固定式导管架平台的适用性,以及研究不能监测的构件对结构关于极限承载力的重要度,为导管架平台的结构整体安全和风险评估提供有效参考。 This paper introduces a damage detection technique, Online Montoring. With example of five simplified jacket platforms with different configuration and an actual North Sea Claymore CPP jacket platform, the natural frequencies of platform are calculated considering the influence of the initial imperfection and additional water mass, and nonlinear pushover analyses are also made to aquire the uhimate strength of intact platform and the influence of member failure on it with large- scare nonlinear FE software ABAQUS. All these aim to test whether the above--mentioned structures are applicable for OLM technique and to study the criticality of undetectable components, under structure's ultimate strength. Thus an effective method of evaluating the safety and risk of integral structure of jacket platform is provided.
