摘　　要：有粘结预应力技术作为国家住建部大力推广的"建筑业10项新技术"之一,在近年来获得了较广泛的应用,取得了较好的技术经济效果。本文结合工程实例,阐述了有粘结预应力技术在折线形屋架施工中的应用,探讨了后张法有粘结预应力施工技术难点及操作要点,并通过效益分析展示了预应力技术的广阔发展应用空间。Bounded pre-stress technology is one of ＂10 new technology of building industry＂ which is developed in MOHURD. It was widely used recent years, and have better effect of technology and economic. The paper introduced the application of bounded pre-stress technology in mansard roof truss by an example, discussed the technical point and operation point of post-tension bounded pre-stress construction. Lay out future development of pre-stress technology by the benefit analysis.
