摘要
本文研究了不同的混凝土碳化指数分布的影响以及影响混凝土碳化指数的主要因素 ,提出了其碳化指数的不确定性模型 ,通过对国内外 14 3组混凝土碳化实验数据的统计分析 ,确定了相应的概率分布模型 ,这将为服役钢筋混凝土结构的耐久性评估提供科学的依据。
? The necessity of studying concrete carbonation index is first discussed in this paper.Then,a probabilistic model is presented on basis of the statistic analysis of the 143 concrete carbonation experimental data from the other articles and a probability formula is given for calculating the reliability and life of the concrete element.The results from this paper show that the concrete carbonation index yields with the lognormal distribution.By the way,the reliability for concrete durability is also calculated Besides,A determined concrete carbonation index is suggested in the paper for engineering to calculate the concrete carbonation depth. 〔
