In this paper, carbon fiber strengthening technology is used to strengthen the reinforced concrete which cracked because of freezing action.
采用碳纤维加固技术，对因受冻害而发生开裂的混凝土结构进行了加固处理。
Enlarging concrete section, enveloping iron and strengthening with carbon fiber sheet are the widely-used methods to strengthen concrete beam.
对于混凝土构件而言，常用的加固方法有：混凝土加大截面法、外包钢加固法、碳纤维布加固法等。
