摘　　要：苏岭山大桥为下承式钢桁系杆拱桥,结构复杂,采用整体节点设计,经过初步分析选取3种钢梁架设方案,通过对架设各阶段进行详细分析计算,结合该桥的结构特点、水文地质条件,根据结构受力、施工难度、经济性及工期等方面的综合比较及分析,确定该桥最合适的施工方案。Sulingshan Bridge is a through steel truss tied arch bridge. The structure of the bridge is complex and the integral joint design is adopted. Three erection schemes of steel beams are selected after preliminary analysis. Detailed analysis and calculation of steel girder erection stage are carried out. According to the structural characteristics and hydrogeological conditions of the bridge, the most suitable construction scheme of the bridge is determined by comprehensive comparative analysis of structural stress, construction difficulty, economy and construction period.
