CEGB

Abstract The assessment of the integrity of structure containing defected are widely used for engineering structure Based upon the ideas of the concept of CEGB/ R6, the failure assessment curve ( FAC) of weldments is analyzed by elasto plastic finite element computations.

含缺陷结构的完整性评价是实际工程中经常遇到的问题，参照CEGB／R6的方法，用有限元对焊接接头的失效评定曲线进行了计算。

A Research on the Reliability Method of the Pressure Vessels and Piping Defect Analysis Based on CEGB R6

压力容器缺陷评定的可靠性方法研究

It is found that mis match of strength has an obvious affection on the FAC of weldments and the mis matching of strength of welded joints must be take into accouter by using CEGB/ R6 method to assess the integrity of weldments.

材料组配对焊接接头的失效评定曲线有很大影响，因此，应用CEGB／R6的方法对接头进行完整性评价时，应考虑接头的材料组配情况。

The probabilistic safety assessment technology based on R6 method was reviewed in this paper. The current development of CEGB R6 was also introduced. Then, two methods for probabilistic safety assessment were presented.

回顾了基于R6方法的概率安全评定技术，介绍了CEGB R6的最新进展，给出了两种概率安全评定的方法。
