摘　　要：为总结散货船油船协调共同规范(HCSR规范)中整套疲劳评估方法的可靠度或安全余量,本文综合考虑不确定性因素对疲劳寿命的影响,包括热点应力差值方法、主应力选取、海况选取、二次应力等。验证了HCSR规范对疲劳评估保有足够的安全余量,为正在修订的HCSR规范的发展提供相关参考。In order to sum up the reliability or safety margin of the whole fatigue assessment method of common structural rules for bulk carriers and oil tankers（ HCSR）,some uncertainties which have a large effect on fatigue life are overall considered in this paper,including： extrapolation methods of hot spot stress,the principal stress selection,sea state selection and secondary stress. It is proved that HCSR has enough safety margins for fatigue assessment and the relative references are also given to the development of HCSR in process.
