摘　　要：无粘结预应力游动锚变角张拉工艺适用于圆形水工构筑物预应力施工,在武汉三金潭污水处理厂卵形消化池的施工中即采用了该工艺。详细介绍了无粘结预应力筋的预埋方法、伸长值的计算方法以及游动锚变角张拉的施工要点等,为相关施工提供了参考。The unbonded prestressed swimming anchor angle tension technology is applied to the prestressed construction of circular hydraulic structures. The technology was used in the construction of egg-shaped digester of Wuhan Sanjintan WWTP. The embedment of unbonded tendons, the calculation of elongation value, the key points in construction of swimming anchor angle tension and so on are introduced, providing a reference for relevant construction.
