某公路桥梁梁板结构的加固与静载试验

REINFORCEMENT AND STATIC LOAD EXPERIMENT WITH BEAM SLAB STRUCTURE OF A HIGHWAY BRIDGE

文章结合对大跨度桥梁的梁板结构加固处理前后的静载试验,探讨了大跨度梁板结构应用粘贴碳纤维加固技术处理的可靠性.静载试验的内容是测定加固前后梁板结构的混凝土应力和挠度.静载试验结果表明,应用粘贴碳纤维加固技术可提高桥梁的强度和使用寿命,降低其应力和挠度.

In this paper, static load experiments are illustrated and the reliability of CFRP reinforcement technology, used for reinforcing beam slab structure of large span bridge, is discussed. These experiments mainly aim at determining the deflection and stress of beam slab structure before and after reinforcement. Experimental results show that, by pasting CFRP for reinforcement, the service life of the bridge as well as its strength can be raised while its stress and deflection can be reduced.
