| 摘 要： | 通过对拱的平衡微分方程受变形影响的研究，推导出抛物线无铰拱的挠度理论计算公式，并与弹性理论的计算结果比较，说明变形对大跨径拱桥的内力影响不可忽视。对于大跨径拱桥，弹性理论计算已不能正确反映拱结构真实受力情况，应按挠度理论分析计算。

| Abstract: | The influence of deformation on the arch equilibrium differential equation is studied,and the calculation formula of parabola non hinge bridge is derived according to deflection theory and compared with the computative results of elasticity theory.It is believed that the influence of deformation on the internal force of long span arch bridge can not be omitted,and the actual force condition of the arch should be analyzed according to the deflection theory. |

| Keywords: | arch bridge simply supported curi vilineal beam deflection theory |
