| 摘 要： | 根据已有的试验数据,计算了牛狄涛模型、Nagataki模型各参数在相同幅度摄动下的变异系数、敏感性系数和相对重要性系数;分析比较了各参数对混凝土碳化深度预测值的影响大小。建议在实际工程中,应用牛狄涛模型进行混凝土碳化深度的计算较为合理。

| Abstract: | with the existing data,the variation coefficient,sensitive coefficient and relative importance coefficient of all parameters in the Niu Ditao model and Nagataki model are calculated under the same perturbation.Different impacts,which each parameter makes on the theoretical value of the concrete carbonation depth,are compared and analyzed.It is suggested that the Niu Ditao model is better in predicting concrete carbonation depth for actual projects. |

| Keywords: | concrete carbonation depth sensitivity analysis life prediction |
