含缺陷结构完整性的概率评定方法

A PROBABILISTIC ASSESSMENT METHOD FOR INTEGRITY OF STRUCTURES CONTAINING DEFECTS

通过分析Ｒ６结构完整性评定与实际情况的差异，提出了一种新的合缺陷结构完整性的概率评定方法。基于原Ｒ６方法和Ｍｏｎｔｅ－Ｃａｒｌｏ模拟技术，该新方法不仅可以用于结构完整性的定量描述，而且可以指导诸如设计、选材、加工、检测等与被评结构有关的决策过程。

By introducing the differences between the original R6 integrity assessment and real situations,this paper proposed a new pro babilistic assessment method for the integrity of structures containing defects with which quantitative information could be obtained,Based on the original R6 and Monte-Carlo simulation techniques,the new method can be used not only to give a probabilistic description of the integrity state of a structure,but also to guide on decision-making processes for all phases related to the structure,such as design, materials selection, fabrication,inspectin,etc.
