摘要
为了研究复合砂浆预应力钢丝绳对桥梁加固的影响,以某T型梁桥为例进行实桥加固,并建立有限元模型进行模拟,同时对该桥进行荷载试验研究。结果表明复合砂浆预应力钢丝绳加固后的桥梁能够明显提高桥梁的强度和刚度,且施工便捷,值得在桥梁加固领域推广应用。
In order to study the effect of the composite mortar prestressed steel wire rope on the bridge reinforcement, a T-shaped beam bridge is taken as an example to carry out the consolidation of the bridge. The results show that the bridge strengthened with the composite mortar prestressed steel wire rope can obviously improve the strength and stiffness of the bridge, and the construction is convenient, and it is worthy of popularization in the field of bridge reinforcement.
