摘要
混凝土碳化深度值是评价钢筋混凝土桥梁损伤和耐久性的一个重要指标。本文分析了混凝土碳化的影响因素。基于实测数据建立了碳化经验公式中碳化速度系数的概率模型。依混凝土保护层碳化失效概率,提出了既有混凝土桥梁耐久性预测的一种简便方法。
he depth of concrete carbonization is an important index for evaluating the damage and durability of the reinforced concrete bridges. Influence factors of concrete carbonization are analysed in this paper. The probability model of the coefficient on carbonization speed in the carbonization experiential formula is established on the test data.According to the failure probability on carbonization of the concrete cover,a simple method of durability prediction is proposed for the existing concrete bridges.
