摘要
由于发生质量事故,需对预应力梁进行加固。采用无粘结钢绞线对预应力梁进行体外预应力加固处理,通过工程实践表明,该技术能提高承载能力、加固施工便捷效果好。
Because of quality accident,the prestressed beam must be strengthened. The external prestressing strengthening technology by adopting unbond steel strand is adopted,practice proved that this technology can improve the bearing capacity,the strengthening construction is convenlent,and it＇s effect is good.
