摘要

根据弹性边界且考虑截面抗弯刚度的索振动频率方程推导了索力对其计算模型参数的灵敏度,得到了索力对各参数的不确定度估计公式。系杆拱桥和斜拉桥的索力对比测试验证了索力不确定度估计方法正确性。并开发了索力和索力不确定度计算软件

Abstract

According to the cable vibration frequency equation with elastic boundary conditions, sensitivity of cable tension to the calculation model parameters are derived taking into account the bending stiffness. The cable tension uncertainty evaluation equations of cable tension to each parameter are obtained. The correctness of this cable tension uncertainty evaluation method is verified by check experiment of cable tension test on a tied-arch bridge and a cable-stayed bridge. Special software is developed for calculating the cable tension and the cable tension uncertainty.
