摘　　要：太原市通达街汾河桥为独塔非对称自锚式空间悬索桥,主桥分主跨和边跨,跨径布置为208m+133m,主桥施工采用"先梁后缆"的施工方法,采用有限元分析软件进行三维建模结构分析和模拟计算,确定了最优体系转换方案,按照拟定的最优方案进行吊索张拉和索鞍顶推施工,顺利完成了桥梁的体系转换。Tongda street suspension bridge in taiyuan is a single-tower asymmetric self-anchored space suspension bridge. The main bridge is divided into main span andside span. The span layout is 208 m + 133 m. The main bridge adopts the construction method of " beam first and cable second". Finite element analysis software was used to analyze and simulate the three-dimensional modeling structure. The optimal system transformation schemeis determined. According to the proposed optimization scheme. The suspender tensioning and cable saddle jacking was carried out,and the system conversion of the suspension bridge was cmpleted.
