摘要
采用钢绞线低回缩量锚固体系可以改善桥梁短预应力束的预应力损失及失效现象,并且该体系具有锚固可靠、施工便利和经济等优点,将会在预应力结构中得到广泛应用。
Applying low-retraction steel wires anchor system can improve the phenomenon of prestressing loss and prestressing invalidation. Meanwhile the system is of some advantages such as dependable anchorage, convenient construction, low cost and so on. Thereby the system will be widely used in prestressed structures.
