摘　　要：体外预应力结构因截面尺寸小,自重轻,预应力筋替换、维护管理方便,预应力损失小,可缩短施工工期以及耐久性高等优点,受到了广泛重视。该文根据重庆某项目,对桥梁体外预应力精细化施工工艺及技术控制展开研究,旨在为该技术的不断提高提供可靠参考依据。The external prestressed structure has the advantages of small section size, light self-weight, convenient replacement, maintenance and management of prestressed bars, less loss of prestress, shortened construction period and great durability. Based on a project in Chongqing, this paper studied the construction tech-nological and technical control of external prestressing of bridges, so as to provide reliable reference for the continuous improvement of the technology.
