摘要
预应力碳纤维板加固技术在桥梁加固中优势明显,能够大幅度提升桥梁的承载力和极限荷载,且能够有效地延缓裂缝的萌生和发展等。论文结合了实际的桥梁加固项目以解析其作用原理。最后对施工操作和未来发展应用提出了几点建议。
The strengthening technique using prestressed Carbon Fiber Reinforced Polymer(CFRP)plate has many noticeable advantages,including significantly increasing the bearing capacity and ultimate load of bridges,effectively retarding the initiation and growth of cracks,etc.This article used a current bridge strengthening project to explain the theory of CFRP.At last,this article also gave several suggestions on construction process and future development.
