摘　　要：采用灰色系统理论方法,对不同水灰比及粉煤灰掺量混凝土的碳化方程进行灰色建模.分别对不同灰色预测模型进行比较分析,依据预测模型精度变化规律,给出了建立混凝土碳化深度灰色预测模型的基本方法.经实例验证,灰色预测模型针对性好、模拟精度高,并可采纳新信息进行新陈代谢,是一种可行、实用、应用范围广泛的方法.Adopting the grey system theory, the carbonation equations for concrete with different water ce- ment ratios and different fly ash contents are established, different grey models（GM）are compared and an- alyzed. Based on the forecasting accuracy variation of the models, a basic method to establish grey forecas- ting model for concrete carbonation depth is therefore proposed. Experiments show that GM forecasting is of good pertinence and high analog accuracy, and is capable of self-updating when new information is found. As a conclusion, GM forecasting is a feasible and practical method with many field of applications.
