摘　　要：结合2006年江苏某高速公路桥梁预应力碳纤维布施工情况,就预应力碳纤维布的抗剥离能力、抗剪能力、结构胶的老化性能等长期性能进行有益的探讨和研究,提出改进措施,并建议目前应谨慎使用预应力碳纤维布。In combination with engineering conditions at a highway bridge in Jiangsu Province in 2006 where prestressed carbon cloth was used, research and discussion are made on stripping resistance and shear resistance of prestressed carbon cloth, aging characteristic of structural adhesive, and other long-term performances, and measures for improvement are proposed. The recommendation is made that the prestressed carbon cloth should be used with caution.
