摘　　要：体外预应力结构作为既有桥梁改造的一种方法,在工程领域得到广泛的应用,本文总结分析了其特点和存在的问题。针对体外预应力结构存在的问题,分析了FRP索的特点,探讨其成为体外预应力索代用品的可能性。FRP索的使用使得体外预应力重新成为新的、具有发展前途的桥梁加固改造方法。The prestressing without bond structure is a kind of method that has Deen widely useu in project field to consolidate bridge. Its characteristics and problems are analyzed in this paper. FRP rope is put forward to solve the problems and its possibility to substitute prestressing without bond structure is discussed. It proves that the use of FRP rope makes prestressing without bond structure a second time to become a brand-new and promising method in bridge consolidation.
