概率模型分析与混凝土碳化

The concrete carbonating and analysis of probabilistic model

根据理论分析认为混凝土构件碳化深度的随机分布物理模型符合正态分布与麦克斯韦(Maxwell)分布.并且作者以大量的浙江及附近地区实际建筑物与构筑物调查资料,对同一环境下、同一强度等级的混凝土碳化深度进行统计分析,验证混凝土碳化概率模型,指出可靠性水平,为混凝土结构的耐久性分析提供依据.

According to the theoretic analysis, it is considered that the physical model of the random distribution of concrete components carbonating depth is coincident with normal distribution and Maxwell distribution. The concrete components carbonating depths are statistically analyzed that, under the same environment and same strength rank, are selected from the inquisitional datum of a great deal of constructions in Zhejiang and regions neighboring, which justifies the concrete carbonating statistic model, brings forward the reliability level, offers key parameter for the endurance analysis of concrete structure.
