以佛开九江大桥和太平大桥为工程背景 ,提出了配筋构件徐变导致的变形及内力重分布计算的极限平衡法思想 ,并结合杆系结构徐变作用的初应变法及有限元理论 ,分析这类结构从开始建造到合拢以后几年内徐变变形和内力变化规律。 Taking Fokai Jiujiang Bridge and Taiping Bridge as engineering background, this paper puts forward the idea of ​​limit equilibrium method of deformation and internal force redistribution caused by creep deformation of reinforcement members. Combined with the initial strain method and finite element theory of the creep effect of the rod structure, Analysis of such structures from the beginning of the construction to close after a few years of creep deformation and internal force variation.
