摘要

摘要: 基于实际腐蚀试验检测数据，通过对数据的统计分析，确定了最大腐蚀深度与平均腐蚀深度比值的概率分布形式。采用K-S检验分析方法，得出了最大腐蚀深度与平均腐蚀深度比值的分布类型。采用钢筋最大腐蚀深度与平均腐蚀深度的比值作为腐蚀深度分析的指标，研究了其比值的概率分布规律，提出了氯离子环境下钢筋腐蚀深度分析的一种新方法，将为钢筋混凝土结构考虑钢筋锈蚀的耐久性评估及耐久可靠性研究提供基础和科学的依据。

Abstract: Based on the test data, by the statistic analysis, probability distribution of the ratio between maximum corrosion depth and average corrosion depth is confirmed.By K-S test, the ratio between maximum corrosion depth and average corrosion depth is concluded.The ratio between maximum corrosion depth and average corrosion depth is regarded as index of corrosion depth;the probability distribution of ratio is discussed, a new method of probability analysis of corrosion depth under chloride environment is proposed, which will provide a scientific basis for durability evaluation and reliability research on RC structures with corrosion of steel bar being taken into account.
