摘　　要：对近年来国内外学者采用预张拉CFRP片材加固受弯构件的张拉方法进行了总结,分析了不同预张拉方法在研究和实际工程中的应用现状和前景,讨论了张拉控制应力、锚夹具的开发和应用以及预应力损失等影响加固效果的关键因素,指出了有待继续研究的问题。State of the art of tension techniques for reinforced concrete bending members strengthened with pre - tensioned CFRP sheets all over the world is reviewed . The application of different kinds of tension methods in research and engineering projects is analyzed. And some key issues which will affect the behavior of reinforced concrete bending members strengthened with pre -tensioned CFRP sheets obviously, such as the pre - tension stress, anchorage or grip and loss of prestress, are discussed. To make full use of this kind of strengtheningtechnique for reinforced concrete structures, future research objectives are proposed.
