摘要
本文计入整体式板桥安全带刚度对弯矩的影响，按带边梁的矩形板分析正交整体式板桥在汽车荷载作用下的弯矩，通过算例分析对比表明：安全带的刚度使板中心纵桥向弯矩减小，横桥向弯矩增大，也使板边纵桥向弯矩减小，而横桥向弯矩变化不大．
In ordcr to take into aeeount the influence of the curb stiffness,a calculation scheme for slab with edge beams is proposed in this paper fur analyzing the moments in slab bridges.Exampls demonstrate that the curb stiffness makes the longitudinal moments deercased in slab bridge and the transverse moments inereased.
