摘　　要：对某高速公路中一跨8米钢筋混凝土简支空心板板底粘贴钢板进行理论分析,通过粘贴钢板前后桥梁各梁板极限抗弯承载力和极限抗剪承载力对比,发现粘贴钢板后原桥承载力提高了75%,但刚度提高效果并不明显。Based on the theoretical analysis of pasting steel plate at the bottom of a reinforced concrete simply supported hollow slab with a span of 8 meters in an expressway,through the comparison of the ultimate bending bearing capacity and ultimate shear bearing capacity of each beam and slab of the bridge before and after pasting steel plate,it is found that the bearing capacity of the original bridge is increased by 75%after pasting steel plate,but the effect of stiffness improvement is not obvious.
