碳纤维加固技术在港口码头改造工程中的应用

Application of Carbon Fiber Reinforcement Technique in Wharf Reconstruction

目前混凝土结构的碳纤维加固技术主要用于陆上土木工程的结构物修复,由于港口码头的水工结构物均处于潮湿、水位变动频繁、氯离子含量较高的环境下,在原有港口工程案例中主要应用该技术加固混凝土结构的次要构件。本工程首次将碳纤维加固技术应用在码头结构物主要受力构件的加固中并取得成功,可为码头水工建筑物的加固修复提供参考。

At present, carbon fiber reinforcement technique is mainly applied in civil engineering structure. Since port marine structure is located in a humid seawater environment with high content of chloride ion and water level being changed frequently, we apply the carbon fiber reinforcement technique firstly in the reinforcement of main bearing structures instead of minor structural members of the original concrete structure. The successful application of the technique may provide references for the reinforcing repair of port marine structure.
