【 摘 要 】

Assembled skewed hollow slab bridge can improve the line shape of the road and adapt to the complex and changing urban street conditions, making the whole route smooth, thus shortening the route and bridge length and improving economic benefits. Assembled skewed bridges are more complicated due to their forces, which leads to more prominent problems in the hinged joints of inclined bridges. When lateral prestressing is applied to the two straight sides of the skewed bridge, it is difficult to achieve the effect of prestressing at the ends. Aiming at this problem, a scheme of reinforcement with transverse prestressed carbon fiber slabs is proposed, and a solid model of fabricated oblique slab bridges is established by ABAQUS finite element software. The results show that the method of transverse prestressing CFRP plate reinforcement is effective for Assembled Skew Hollow Slab Bridge.
