| 摘 要： | 为了改善嵌人式预应力纤维布(FRP)加固技术的不足之处,利用粘结与机械锚固共同工作的原理,在预应力FRP张拉粘贴完毕后,对张拉端进行二次锚固,粘结层硬化后拆除原有锚夹具.为保证锚固端的可靠性,本文对锚固端粘结层的性能进行了理论分析,并对混合锚固端进行了试验研究.研究结果表明:通过改变粘结层的性能,可大幅度提高粘结层的锚...

| Abstract: | In order to improve the deficiency in the technology of embedded prestressed FRP reinforcement,with the principle of anchoring bond and additional mechanical anchoring working together,the tensioning end of prestressed FRP is anchored twice after the tension and bonding of the FRP,then removing the existing fixture and anchor.To ensure the reliability of anchoring,the paper makes a theoretical analysis of the performance of the bonding layer in the anchoring end and an experimental research on hybrid anchor... |
