碳纤维结合体外预应力筋加固空心板梁的试验研究

随着桥梁加固技术的发展,各种加固技术已经日渐成熟,然而单靠一种加固方式进行桥梁加固已经不能满足现在工程的需求。利用粘贴碳纤维和张拉体外预应力筋复合加固的方式对空心板梁进行加固是一种综合、有效的加固方法。通过真型空心板梁试验,研究碳纤维和体外预应力筋两者相结合的加固机理,为复合加固技术的推广奠定了基础。

Experimental Study on Reinforced Hollow Beam with Carbon Fiber Reinforced Polymer and External Prestressed Strand

With the development of bridge reinforcement technology, various reinforcement methods have been matured. However, just relying on one signal reinforcement method cannot meet the current needs of the project. Using carbon fiber reinforced polymer and external prestressed strand to reinforce hollow beam is a comprehensive and effective reinforcement method. Through experiment study on the combined reinforcement mechanism of carbon fiber reinforced polymer and external prestressed strand on the true type hollow beam, the foundation for the promotion of composite reinforcement technology is laid.
