摘　　要：基于三元构件之一斜拉桥的合理成桥状态确定思想,以一次落架模型按最小弯曲能量原理确定的拱梁组合体系吊杆成桥索力作为初始值,然后将其代入逐步落架模型,用影响矩阵法的迭代调值原理进行最终值的确定。并以韶关百旺大桥为例,进行实桥分析计算。Based on the theory for the tensile force of cable-stayed bridges, the tensile force determined by the minimum bending energy methodwith the model installed in is taken as the original value and the (final) value is obtained by the influence matrix method with the model installed later. Taking Shaoguan-Baiwang Bridge as an example, the tensile forces of suspenders of arch-bridges are calculated in the paper.
