摘要： 体外预应力技术发明于本世纪廿年代。到50年代初,在西欧建成了十余座体外预应力砼桥梁。但由于钢索锈蚀等问题的困扰,曾一度放弃了其研究与应用工作。近十几年来,随着诸问题的逐渐解决,体外预应力技术重新受到重视,得到了广泛应用和发展。本文叙述了体外预应力的技术内容,以及在桥梁工程中的应用。
关键词: 体外预应力技术, 桥梁工程
Abstract: The extraneous prestressed technique was invented in the 1920s.More Than ten extraneous prestressed concrete bridges had been constructed by the early 1050s.Because of the corrosion of steel cables and some other problems,its study and application was once put aside.In the recent years,with the problems gradually solved,the technique has regained attention and found wide application and development.This paper deals with the extraneous prestressed technique and its application to bridge engineering.
Key words: extraneous prestressed technique, bridge engineering
