采用增大截面的方法加固无梁板桥

Reinforce a Slab Bridge without Beam by the Method of Increasing the Cross section

本文通过工程实例,详细叙述了某无梁板桥在上部结构刚度及承载能力均已不满足设计要求时的加固方法,并通过计算数据说明该加固方法所能起到的加固效果。

Through engineering examples, this paper describes in detail a slab bridge without beam in superstructure stiffness. Bearing capacity could not satisfy the design requirements of strengthening methods.The calculated data shows that the method can act as a reinforcement effect.
