[摘要] 随着城市化进程步伐加快，我国工程结构加固改造的发展也日益重要。建设工程的加固是一个局部或全部结构力学体系上的措施，通过工程加固技术来实现其使承载力、使用功能、抗疲劳性能、抗震性能得到恢复或改善的目的。主要阐述工程加固改造的基本理论，并对实际工程做了试验研究。

Abstract: With the accelerated pace of urbanization, structural reinforcement and reconstruction of engineenng development is becoming increasingly important. Reinforcement construction is a part or the whole structure on the mechanical system of measures, strengthening technology through engineering to achieve its making capacity, function, fatigue performance of the seismic performance of recovery or improvement purpose. The basic theory of reinforcement and reconstruction projects is described, so as a test ofthe actual project.
