摘要：含缺陷压力管道安全评定的方法较多，主要有极限载荷控制的塑性失效准则、断裂力学J积分的评定方法、英国R6双判据准则评定方法、美国ASME规范评定方法、参数不确定性缺陷的安全评定方法等。文章对这些方法加以简要的概括和评述，并分析了有些方法之间的区别与联系，同时指出工程化、可靠性和智能化是当前含缺陷压力管道安全评定方法的发展趋向。

Abstract：Safety assessment methods relating to the pressure piping with defects are various；including mainly the plastic failure criteria for control of limit load，J-integral in fracture mechanics method，a well-known engineering safety assessment procedure R6 in British，America ASME standard assessment method，uncertain parameters defects assessment method and so on.These methods were reviewed and summarized；some difference and relations were analyzed.Meanwhile，the developmental trend of its engineering，reliability and intelligence was also presented for the safety assessment methods of pressure piping with defect.
Key words：pressure piping；defect；reliability；safety assessment；situation and development
