碳纤维布在高桩码头加固中的应用

Application of carbon fiber cloth in reinforcement of high-pile wharf

早期建设的高桩码头结构由于腐蚀、老化、过载、疲劳等原因导致损伤,影响码头的使用功能,针对这一问题进行了码头构件的加固研究。结合高桩码头加固实例,采用现场试验及数值模拟方法,通过加固前后混凝土构件挠度及应力变化,分析了粘贴碳纤维布对损伤构件的加固效果。结果表明,粘贴碳纤维布可有效降低混凝土构件的挠度及应力,对损伤构件有良好的加固效果。

The early high-pile wharf structure is damaged due to corrosion, aging, overload, fatigue and other reasons, which affect the function of the wharf. Regarding these problems, the reinforcement of wharf components is studied. Combined with the reinforcement example of high-pile wharf, by the field test and numerical simulation method, the reinforcement effects of carbon fibers cloth on damaged components are analyzed through the deflection and stress change of concrete components before and after reinforcement. The results show that sticking carbon fiber cloth can effectively reduce the deflection and stress of concrete components, and has a good reinforcement effect on damaged components, which can provide a reference for the repair of similar wharfs.The results show that CFRP can effectively reduce the deflection and stress of concrete members, and has a good reinforcement effect on damaged members.
