摘　　要：为了改善北京工人体育场照明效果,在原钢结构雨棚上增加灯架,灯架形式选用梭形桁架和拉索组成的悬索结构。详细介绍了预应力灯架的施工流程和索长的确定方法、张拉设备选用以及预应力张拉操作要点。采用MIDAS有限元分析软件进行施工仿真计算。同时对张拉过程进行施工监测,为梭形桁架柱的稳定研究提供数据支持。In order to improve the stadium lighting effects, lighthouse is designed on the original steel awning, which is composed of shuttle shape truss and cable as suspension cable structure. Construction process and cable length, tension equipment, key points for operation were introduced in detail. Further, simulation calculation was done by MIDAS software, and construction monitoring was done during tension. Both of them provide reference for stability research of shuttle shape truss.
