摘　　要：通过试验梁试验研究粘贴钢板加固预应力混凝土桥梁的加固效果。试验采用分级加载的方式,对试验梁加固前后各级荷载作用下控制截面的应变、挠度和裂缝宽度进行详细加载测定。分析加固效果及其变化规律,可为今后类似工程的加固设计提供参考。The reinforcement effect of the prestressed concrete bridge strengthened by the steel plate is studied by the test beam. In the test,the strain,deflection and crack width of the control section of the test beam are measured before and after the reinforcement. The analysis of reinforcement effect and its variation law can provide references for the design of similar projects in the future.
