混凝土结构的碳化模式与碳化寿命分析

Model and reliability analysis for carbonation of concrete structures

利用我们近几年对旧建筑物检测积累的资料和国内外的有关资料，建立了根据混凝土立方体抗压强度预测碳化深度的数学模型和碳化深度标准差的经时变化模型。分析了混凝土构件的碳化控制可靠度，并给出了估计混凝土构件碳化寿命的方法。

Based on the statistical analysis of collected data in recent years for inspection of concrete structures in used,this paper presents two models-the mathematical model to predict carbonation depth with the concrete cube strength and a carbonation depth standard error model changinng along with time.Furthermore,the paper analyzes carbonation reliability life of reinforced concrete members and gives a method to estimate carbonation life of reinforced concrete members.
