摘　　要：本文介绍无粘结预应力技术在我国应用概况．并根据几个无粘结预应力技术在桥梁方面成功的设计及施工实例，分析了无粘结预应力技术在桥梁方面应用的广阔前景．简要介绍了我国目前有关无粘结预应力技术的设计施工规程、无粘结预应力筋束的生产工艺及我们有关无粘结预应力砼梁斜截面抗剪和抗疲劳方面的科研成果，希望把我们的研究成果应用于生产实践，使这项新技术在我国得到进一步推广，带来更大的社会经济效益．This paper expounds the survey on the applying of the unbonded prestressed concrete technique in China. and it gives some examples of bridges constracted by this technique. These examples make known that this technique can be used in bridge engineering and havs a vast vista. This paper simply recommends the rules of the design and construction of the unbonded prestressed concrete. At the end, it gives the results of experimental research on ultimate shear strength and fatigue strength of the un bonded partially prestressed concrete beams.
