碳纤维筋在危桥加固中的应用

Application of carbon fiber reinforcement in the dangerous bridge strengthening

碳纤维筋桥梁加固是一项新的应用外粘高性能碳纤维复合材料增强结构技术,碳纤维筋与高强聚合物砂浆的联合使用充分利用了纤维棒筋的抗拉伸强度、聚合物砂浆的快凝强度和砂浆与钢筋混凝土结构的温缩模量的近似特性,提升钢筋混凝土结构的承载能力,达到维修、加固、利用与修旧翻新的综合作用,提升桥梁加固结构安全领域的技术水平。

Carbon fiber reinforced concrete bridge is a new technology,which is used to improve the tensile strength of fiber reinforced concrete,and to improve the bearing capacity of reinforced concrete structure,and to improve the safety of the bridge structure in the field of maintenance.
