摘　　要：179摩天轮高179m,轮缘直径170m,建成后将成为世界最高的摩天轮。179摩天轮采用刚性轮辐(刚性桁架硬支臂)与钢索混合结构形式。大型摩天轮的安装方案与摩天轮的结构设计密切相关,因此,在结构设计阶段就必须制订合理的安装方案。179摩天轮采用立面旋转安装法安装,并对8个施工步独立静止状态进行有限元分析。借助有限元软件ANSYS来模拟分析计算硬支臂和轮缘安装后不同安装位置静止情况下的等效应力、挠度、结构屈曲,由计算结果可知,不同安装位置摩天轮的结构安全可靠。The 179 Ferris Wheel is 170 min diameter and 179 m in height.It will be the world＇s highest ferries wheel upon completion.This ferris wheel applies the rigid spokes（rigid truss arms）combining with steel cables in the structure.The giant wheel installation is closely related to the structural design of the wheel structure.Therefore,a reasonable installation plan must be made at the structural design stage,to ensure structural safety and reliability.Rotation installation method is used to the 179 Ferris Wheel,and finite element simulation analysis on eight independent stationary states during installation is carried out.Equivalent stress,deflection and buckling analysis of the 179 Ferris Wheel are evaluated at different installation positions using ANSYS software.The analysis result indicates the whole installation process is safe and reliable.
