摘　　要：针对某污水处理厂在无粘结预应力薄壁圆形二次沉淀池施工中,出现预应力钢绞线实测值比理论伸长值系统性偏大的现象,进行全面、系统地分析,找出了产生实测伸长值系统性偏大的原因,为类似工程提供了经验。In construction of a prestressed thin-wall round secondary sedimentation tank without bond in a sewage disposal plant,the measured elongation of prestressed steel strand is systematically bigger than the theoretical value.After comprehensive and systematical analysis,reasons for systematically bigger measured elongation are found out,providing referential experiences for similar projects.

关 键 词：无粘结预应力 二次沉淀池 伸长值
