摘　　要：援柬埔寨体育场项目南、北两侧各设1座高99m异形索塔结构,根据其截面形状、几何尺寸、面积等沿高度连续变化的结构特点,在26.4~77.5m段采用"截面递减爬升平台+局部挂架"的造塔平台,为定型模板高空组装、钢筋绑扎提供了操作空间,实现了工程的预期目标。A special-shaped cable tower structure with a height of 99 m is installed on both the north and south sides of Cambodian Stadium Project.According to its structural characteristics that sectional shape,geometric size and area continuously change along the height,the tower building platform of "curve inclined climbing platform + local pylons"is adopted in the stage of 26.4 ~ 77.5 m.It provides operation space for the high-altitude assembly of the shaped formwork and the binding of steel bars,which achieves the project’s expected goal.
