摘要
纤维布预应力加固技术是对传统的简单粘贴纤维布加固技术的革新,它能充分发挥高强纤维布作用,极大地改善被加固混凝土结构的性能。采用一种新型的纤维布预应力锚固和张拉方法,可将CFRP的应力张拉到1600M Pa以上,锚固、张拉的各项指标均比较理想。
The reinforcing technique of pre-stressed fiber cloth, a renovation to the traditional reinforcing method of affixed fiber cloth, can make full use of the high strength of the cloth, and improve the performance of reinforced concrete structure greatly. By the method of pre-stressed fiber cloth introduced in this article, the stress of CFRP can be tensioned to above 1600 MPa, meanwhile, all parameters of anchorage and tension are very perfect.
