摘　　要：以贵阳花溪二号桥为研究对象,用桥梁博士结构程序模拟混凝土的收缩徐变对预应力损失的影响,得出混凝土龄期在80 d后收缩徐变对预应力损失影响基本稳定的结论,并提出了相应的施工建议,以指导实践。Taking Guiyang Huaxi No. 2 Bridge as the research target, it simulates the impacts of shrinkage and creep on prestressed loss with bridge structure program, obtains an conclusion that the impact of shrinkage and creep of concrete age after 80 d on prestressed loss is basically stable, and puts forward corresponding construction proposals, with a view to guide practice. ＂
