摘要
从施加预应力阶段、活载作用阶段两方面分析了体外预应力加固的作用机理，介绍了加固体系正常使用阶段的有关计算，表明了体外预应力加固技术具有很好的应用前景。
From two aspects： prestress apply stage and live-loads action stage the impacting mechanism of extraneous prestressed strengthening technique is analyzed. Some calculations are made for strengthen system in service period of bridge. Results show this strengthening technique has good application prospect.
