摘　　要：研究轮辐索支承的摩天轮结构传力特点,引入连续化方法,将离散设置的索展开为连续分布的纤维,建立轮盘结构在运营荷载作用下的平衡微分方程,求解得到了结构内力和位移的近似解析解。通过数值算例对解析解进行了验证,表明本文提出的解析解计算精度较高。本文的解用公式揭示了摩天轮结构荷载与内力、变形之间的内在关系,具有明确的物理意义,可以为摩天轮结构设计提供参考。The continuation method is introduced to the analysis of spoke cable stayed ferris wheels subjected to operation loads.By proposing hypotheses of continuous rim and spokes of Ferris wheels,the equilibrium differential equations are derived and solved to achieve the analytic solution of the forces and deformations.Numerical examples are conceived to verify the present solution.The analytic results show that they fit well with the numerical ones.The present solution reveals the intrinsic relationship between the loads,forces and deformations of the wheels.The solution has definite physical meaning to be easily understood.The present method is expected to be a complementary solution to the design and construction of ferris wheels.
