本文提出了一种综合判断钢筋腐蚀的新方法——基于多因素的混凝土中钢筋腐蚀判别方法。该方法综合考虑影响钢筋腐蚀的多个因素,首先通过主成分分析的方法提取特征参数,然后建立基于支持向量机的钢筋腐蚀状态分类器,并在实际工程中检验了模型的判别准确率,结果表明主成分分析与支持向量机结合的方法具有运算简单,判别准确率高的优点。
In the paper,a method of evaluating corrosion in reinforced concrete is introduced, it takes multi-factors into account. The first place is to select the character parameters of corrosion severity system based on principal component analysis. And then it establishes the classifier of corrosion severity by using support vector machine. At last the method is used in evaluating the corrosion severity of a real building. The results show that the method based on principal component analysis and support vector machine has the advantage of the more accuracy rate of classification and the more simple and efficient arithmetic.
