海上结构物损伤检测的探测概率分析

针对海上结构物实际存在的主要损伤形式，提出了不同的探测概率表达式；通过定义检测质量，运用模糊数学理论分析了人的失误因素对检测的影响，得到了检测质量的表达式．为验证表达式的有效性及准确性，利用某平台的现场检测中人的失误因素对检测质量影响的评估数据结果，分析并确定某些参数，从而确定了探测概率．分析结果表明，文中提出的检测质量及探测概率模型较好地反映了各种因素对检测的影响，为海上结构物进一步检测维修的可靠性分析等提供了基础及依据．

Estimation of Probability of Defect Detection in Offshore Structural Inspection

This paper presents the expressions for the POD of four different damaged forms which mainly exist in offshore structural components. Fuzzy set theory is applied to estimate human errors through definition of inspection quality .Expression of inspection quality is achieved.To verify the validity and correctness of the expressions ,we use the data from an offshore platform field inspection of four kinds of damages and evaluation results of human errors affecting inspection quality to estimate the parameters of the POD.The results show that the presented models can provide the basis for further study of offshore structural inspection reliability.
