摘　　要：CFRP材料已被广泛应用于RC材料抗弯加固中,该方法能有效提高构件的极限承载力,但CFRP与混凝土材料粘接力不足导致剥离破坏易发生。为了延缓甚至防止此现象出现,提高CFRP片材的利用率,目前提出了多种提高粘接力的界面结合技术。本文对各种混凝土界面糙化方法和CFRP片材锚固法进行总结,并对不同的方法进行对比分析。CFRP materials have been widely used in RC materials for flexural reinforcement,this method can effectively improve the ultimate bearing capacity of the component,but the lack of adhesion between CFRP and concrete materials causes peeling failure to easily occur.In order to delay or even prevent this phenomenon and increase the utilization rate of CFRP sheets,a variety of interface bonding technologies to improve adhesion have been proposed.This paper summarizes various concrete interface roughening methods and CFRP sheet anchoring methods,and compares and analyzes different methods.
