| 摘 要： | 文章以神农溪斜拉桥索塔为研究对象，运用有限元分析软件Midas／civil建立索塔的空间模型，对索塔有临时支撑和无临时支撑两种施工方式进行模拟分析，结果表明：在索塔斜塔柱施工过程中添加临时支撑钢管减小了斜塔柱的应力，优化了索塔的应力状态。

| Abstract: | With Shennongxi cable-stayed bridge pylon as the research object,the article used the finite element analysis software Midas/Civil to establish the pylon＇s spatial model,cond- ucted the simulation analysis on two construction plans of pylon with temporary support and without temporary support,and the results showed that：the temporary support steel pipe in the pylon leaning-tower column construction process can reduce the stress of leaning-tower column and can optimize the stress state of pylon. |
