摘要
混凝土结构截面上碳化深度分布的确定，是进行混凝土结构截面等耐久性设计的基础．按照传质原理，建立了混凝土结构截面上CO2的二维扩散传质方程，并利用有限元方法作了混凝土构件截面上碳化深度分布的计算．算例表明角区混凝土的最大碳化深度约为一般边碳化深度的1．4倍．
It is a foundation of equal durability design of the section about concrete structures to detendnate the distribution of concrete carbonization depth at the section. According to the principle of conducting mass, two - dimensional equation of diffusing conducting mass is found. By use of the principle of finite element, distribution of concrete carbonization depth is calculated. The calculation result states that the maximum carbonization depth in the comer is 1 .4 times as deep as that in the general edges.
