摘　　要：通过对预应力粘钢加固钢筋混凝土梁的荷载试验,表明预应力粘钢加固梁的承载能力较普通粘钢加固梁略有提高,但对梁在正常使用阶段内的受力状态(挠度、裂缝宽度等)有明显的改善,同时能充分利用加固钢板的抗拉强度。The loading experiment of reinforced concrete beams affixed with steel plates and strengthened with prestresses demonstrates that their loading capacities are improved a little compared with normal concrete beams affixed with steel plates, however beams＇ flexures and crack widths are decreased greatly and tensile strengths of the steel plates are fully utilized.

关 键 词：预应力粘钢加固 张拉控制应力 承载力 挠度裂缝
