摘　　要：为准确评估含缺陷汽轮机转子的安全性与可靠性,提高汽轮机转子设备监理工程的服务质量,根据行业标准,本文从缺陷的失稳断裂评估与疲劳扩展寿命两方面对含缺陷汽轮机转子进行了安全性评估分析。基于CAP1400项目汽轮机转子设备监理实践,分析了对含缺陷汽轮机转子安全性评定方面监理的难点与重点,提出不可将裂纹扩展寿命估算结果代替缺陷的安全性评定,以及选取适当边界条件,该结论对提高汽轮机设备监理服务质量与保障机组稳定运行有着重要的现实意义。In order to accurately evaluate the safety and reliability of defective turbine rotor and improve the relevant supervision quality, this paper presents an analysis in terms of unstable fracture evaluation and fatigue life according to the standard of the industry. Based on the experience in supervising the turbine rotor of the CAP1400 project, the paper analyzes the key points for safety evaluation and points out that the crack propagation life estimation should not replace the defect safety evaluation.Proper boundary conditions should be selected. This conclusion means a lot in improving the supervision service quality and keeping stable machine operation.
