为明确缺陷尺寸对不同剩余强度评价方法保守性的影响，针对一系列不同长度和不同相对深度的缺陷，采用改进的ASME B31G准则、DNV RP F101规范和PCORCC方法分别对其进行剩余强度评价，比较发现缺陷的长度和相对深度对3种剩余强度评价方法的保守性影响十分显著，尤其是对传统认为的过分保守的ASME B31G方法影响最为显著。

In order to know the effect of defect sizes on different residual strength assessment methods'conservative property, the modified ASME B31G code, DNV RP F101 standard and PCORRC method are used to calculate the residual strength of de-fects with a series of different relative depths and different lengths.The results show that the length and relative depth significant-ly influence the conservatism of the three assessment methods, and particularly have the most significant impact on ASME B31G code which is considered too conservative in the past.
