无粘结网绞线环配筋摩擦、锚固损失和影响长度试验研究

THE EXPERIMENTAL RESEARCH ON THE LOSS OF FRICTION AND ANCHORAGE AND THE AFFECTED LENGTH OF CIRCULAR PRESTRESSED UNBONDED TENDONS

结合青岛海泊河水处理厂无粘结预应力工程，通过试验和理论分析，揭示了无粘结预应力筋摩擦锚固损失和锚固损失影响长度等各种影响因素的关系，并提出了摩擦锚固损失的计算方法。

The relationship between prestress loss due to friction and anchorage and affected length by anchorage deformation is revealed through experimemtal and analysis studies of the unbonded prestressed concrete engineering of QingDao Haibohe Poluted Water Disposal Work.The caculating method of prestress loss due to friction and anchorage of circular prestressed structure is given.
