摘要
利用δ广义函数定义,考虑了索的几何非线性、建立小垂度索的平衡微分方程,通过直接积分法求得安装阶段和使用阶段索的轴线方程的样条函数表达式,安装阶段考虑荷载的影响;使用阶段按本文的挠度理论计算更符合实际。
Based on function and considering geometric nonlinearity of cable, the paper presented cable deflection equation. By the direct calculus method, the paper obtained the function formula of cable axial equation when cable was in the phase of installment and operation. The loading effet was taken into consideration in cable installment while the deflection theory proved more practical in cable operation.
