结合某预应力混凝土连续箱梁桥开裂和下挠病害处治的加固实践,介绍了该桥的加固方法,对加固前后的应力和挠度计算结果进行了对比分析,验证了加固效果的可靠性,该桥的加固实践可为同类型桥梁的加固处治提供参考。 Combined with the consolidation practice of crack treatment and deflection treatment of a prestressed concrete continuous box girder bridge, the method of reinforcement of the bridge is introduced. The calculation results of stress and deflection before and after reinforcement are compared and the reliability of the reinforcement effect is verified. The strengthening of the bridge can provide reference for the reinforcement of the same type of bridge.
