摘　　要：通过实桥加固试验,详细测试腹板粘贴钢板加固法在降低主梁控制截面应力、挠度和裂缝宽度方面的效果。试验结果表明:采用腹板粘贴钢板加固方法,对降低开裂预应力混凝土结构的应力、挠度和裂缝宽度较为有效,该方法还能够有效提高主梁的抗弯刚度和耐久性,可为今后类似工程提供参考。Through the strengthening test of solid bridge,the effect of Web bonded steel plate strengthening method on reducing stress,deflection and crack width of main girder control section is tested in detail. The test results show that the method of strengthening steel plate with web plate is effective to reduce the stress,deflection and crack width of the cracked prestressed concrete structure,which can also effectively improve the flexural rigidity and durability of the main beam,and can provide reference for similar projects in the future.
