摘　　要：缓粘结预应力技术是有粘结、无粘结施工技术发展到一定阶段的创新,其施工工艺简单,质量容易控制,节点布置灵活,耐久性能优异,工程经济性强。但预应力专业施工单位一般规模不大,施工水平参差不齐,施工质量不易控制,因此,施工质量控制是缓粘结预应力施工的重点。Slow bonding prestressed technology is an innovation in the development of bonded and non bonded construction techniques to a certain stage.Its construction process is simple,quality is easy to control,node layout is flexible,durability is excellent,and engineering economy is strong.However,prestressed professional construction units generally have a small scale,uneven construction levels,and difficult to control construction quality.Therefore,construction quality control is the focus of slow bonding prestressed construction.

关 键 词：缓粘结 预应力 钢绞线 张拉
