摘　　要：公路规范一直缺少关于偏心受压构件稳定性计算的公式 ,只是用限制偏心矩增大系数的方法来保证构件的稳定性 ,文中分析了这种计算方法的可靠性 ,指出了规范方法存在的缺陷 。There isn't a formula for the stability calculation of eccentric compressive members in the code for design of highway bridges,so the stability of the members is only ensured by the restriction of increment factor of eccentric distance. After analyzed the reliability of the calculation method in the code, the limitation of the method is pointed out and the solution method is presented.
