预应力连续刚构桥梁底板加固

Reinforcement of Prestressed Continuous Rigid Frame Bridge

某预应力连续刚构特大桥,左幅箱梁底板进行预应力施工时,一个节段出现小范围病害,经论证,确定采用粘贴钢板进行加固。加固后,控制了病害的进一步发展,使大桥得以顺利完工,效果良好。

In the prestressed construction of Left frame girder floor of a certain prestressed continuous rigid-frame super-large bridge,there is a small area of disease in one segment.After verification,it was confirmed that the steel plate was used for reinforcement.After the reinforcement,it controlled the further development of the disease and enabled the bridge to be successfully completed.
