碳纤维布在某运河大桥箱梁加固中的应用

Application of carbon fiber reinforced plastic retrofit method in a canal bridge

碳纤维材料(CFRP)加固混凝土结构技术是一项新型结构加固技术。介绍了某运河大桥利用碳纤维布进行抗剪加固的设计方法、施工工艺及施工过程中的质量控制。通过加固前后的动载试验表明加固取得了理想的效果。

Concrete structure strengthened with carbon fiber reinforced plastic (CFRP) is a new retrofit method in the field of civil engineering. In this paper, the design method, construction techniques and quality control of CFRP retrofit method in a canal bridge are introduced. By the dynamics test it shows that the retrofit effect takes hold.
