根据一些常规的混凝土构件检测参数和耐久性影响因素，结合熵投影寻踪动态聚类方法的特点，建立了钢筋混凝土构件的评估模型。通过工程实例计算，可以看出该模型可以很好地适用于钢筋混凝土构件的耐久性等级评估，投影寻踪动态聚类法切实可行，且它是一种由样本数据驱动的探索性数据分析方法，区别于大部分先假定等级再证实归类的评价过程，不需要依赖经验判断，开辟了一条利用多因素分类评价混凝土构件耐久性问题的新途径。

It is of very important economic value and social significance to evaluate the durability of concrete members . The evaluation model of reinforced concrete members was established in accordance with some testing parameters of con-ventional concrete members and the influencing factors of durability ,as well as in combination with the characteristics of entropy projection pursuit dynamic cluster (PPDC ) method .Practical engineering calculation indicates that the model is suitable for durability assessment of concrete members and the PPDC method is feasible . PPDC is an exploratory data analysis method powered by the sample data ,which is different from the other evaluation processes with presumed classi-fication grades being confirmed by the subsequent actual evaluation , it does not rely on experienced subjective judge-ments .PPDC proposed a new way to solve the evaluation problem of multiple factors .
