介绍了曹州桥的主要加固方法——钢拱架承托法,该方法比传统增大截面方法节约成本,避免了自重增加较大、新老混凝土黏结不好和加固结构在使用中应力滞后等问题,且在施工时不中断交通,可以有效地减小原桥结构混凝土应力,较大地提高原桥的承载能力,综合加固效果好。 The main reinforcement method of CaoZhou bridge - steel arch support method is introduced, which saves cost compared with the traditional method of increasing the cross section, avoids the increase of self weight, the bad bonding of new and old concrete and the stress lag in the use of the reinforced structure Problem, and in the construction without interruption of traffic, can effectively reduce the stress of the concrete structure of the original bridge structure, greatly enhance the carrying capacity of the original bridge, the comprehensive reinforcement effect is good.
