体外预应力技术在桥梁加固中的应用

随着我国经济的高速发展，交通量迅速增大，桥梁负荷越来越重，导致桥梁损伤劣化现象日益普遍和严重，因此桥梁的加固工程变得十分重要。结合桥梁工程实例，对桥梁加固工程中体外预应力技术进行了分析，以供同行参考。

Application of External Prestressing Technique in Bridge Reinforcement

With the rapid development of economy in China, the traffic volume is increasing and the bridge load is heavier and heavier. It causes the damage of bridges is becoming more common and serious. Therefore the bridge reinforcement becomes very important. Combined with one bridge as an example, this paper analyzes the technique of external prestressing which is used in bridge reinforcement engineering, so as to provide reference for peers.
