[提要]  依照經(jīng)典的單向碳化深度計(jì)算模式的推導(dǎo)過(guò)程，推出角區(qū)混凝土最大碳化深度的計(jì)算公式，在分析影響混凝土碳化因素的基礎(chǔ)上，建議了碳化深度的經(jīng)驗(yàn)計(jì)算公式，并依據(jù)實(shí)測(cè)數(shù)據(jù)建立了一般邊碳化深度值的隨機(jī)過(guò)程模型，依類比法建立了角區(qū)最大碳化深度值的隨機(jī)過(guò)程，為預(yù)測(cè)提供了一條可靠途徑。
[關(guān)鍵詞]  既有混凝土結(jié)構(gòu) 碳化深度 預(yù)測(cè)

Carbonization predicting on existing concrete structures is a key index for predicting the future state
about concrete structures. Based on the classics deduction course about one direction carbonization, a calculation formula of the maximum carbonization depth at the corner is obtained. In the light of analyzing the factors influencing concrete carbonization, a experiential calculation formula is recommended, and a stochastic process model of general edge carbonization depth is set up according to the measurement data in situ. A stochsatic process of the deepest carbonization in the comer is formulated with the method of analogy. A reliable way is provided for predicting carbonization depth.
Keywords: existing concrete structure; carbonization depth; predicting
