摘要
通过分析7座在役混凝土大坝不同部位混凝土碳化深度检测结果,对比了Lesache de Fontenay模型、Smol-czyk模型、中国建筑科学研究院模型的混凝土碳化深度计算结果,得出Smolczyk模型预测在役混凝土结构碳化深度与实测值契合度较高,并根据工程检测结果对Smolczyk模型进行了修正,建立并验证了基于混凝土强度检测结果的在役混凝土大坝碳化深度预测模型,根据碳化深度预测模型推导出了碳化寿命预测模型.
Abstract
Based on the analysis of the concrete carbonation depth detection results at different parts of 7 in-service concrete dams,this study compares the calculation results of Lesache de Fontenay model,Smolczyk model and China Academy of Building Research model.It is concluded that the Smolczyk model has a good fit for predicting the carbonation depth of in-service concrete structures.The Smolc-zyk model is modified according to the detection results,and the prediction model for the carbonation depth of in-service concrete dams based on the concrete strength test results is established and validat-ed.According to the carbonation depth prediction model,the carbonation life prediction model is de-rived.
