预应力碳纤维布施工探索

预应力碳纤维布应用于桥梁加固领域，目前处于起步阶段，尚无成熟的施工工艺和相应的预应力碳纤维片材施工规范。结合某特大桥的预应力碳纤维布施工，对预应力碳纤维布施工方案和施工中所遇技术难题进行了阐述，结果表明，采用该方法加固的桥梁结构的承载能力和刚度均有所提高，能满足桥梁安全运营的要求。

Exploration of Construction of Strengthening Concrete Beams with Prestressed CFS

At present, application of prestressed carbon fiber sheet in bridge reinforcement is in starting stage, there is no mature construction techniques and construction specifications of CFS.Combined with CFS construction of a super major bridge, this paper analyses the construction method and problems.The results show that the bearing capacity and stiffness of bridge reinforced by CFS are all improved, which can satified the bridge operation.
