摘　　要：阐述了钢筋混凝土转换层大梁加固采用体外锚固有粘结预应力筋的设计、计算和技术特点。工程实践表明,该加固方法不仅解决了一般加固结构中的应力应变滞后现象,且施工方便、技术合理、加固效果可靠。The paper Discusses the strengthening technology of external-anchoring bonded prestressed reinforcement used in the reinforced concrete transfer-floor girder, and also introduces the design,calculation and technical characteristics of the method. The engineering practice shows that the technology can avoid stress-strain lagging in the ordinary strengthening construction, and makes the engineering construction convenient and reasonable. As a result,the strengthening effect is safe and reliable.
