摘　　要：探讨了建立预测混凝土碳化深度的实用随机模型并进行其有关系数分析研究的基本方法,目的是预测混凝土剩余碳化寿命,以对碳化破损混凝土结构在及时作出维修加固的决策方面提供科学依据。通过西园隧洞的实例验证,该预测方法是实用的、可靠的,可为其他类似新建工程的混凝土耐久性设计、混凝土结构服役期的抗碳化维护等方面提供参考借鉴。Study the basic method on building the practical stochastic model of predicting the concrete carbonation depth and the analysis and research of correlation coefficient about that.Its purpose is to predict the concrete residual carbonation life and provide scientific basis for maintaining and strengthening the concrete structure which is carbonized and damaged in time.The example of Xiyuan tunnel shows that this predictive method is practical and reliable.It can provide the reference for the design of concrete durability and maintaining the anti-carbonation capacity of concrete structure in the other similar new projects.

关 键 词：混凝土碳化深度 实用随机模型 剩余碳化寿命
