Study on Influence of Uneven Foundation Settlement on Upper Ferris Wheel

摘要:

近年来，与商业综合体相结合的屋顶摩天轮日渐增多，因此对摩天轮与商业综合体之间相互影响的分析凸显重要。主要研究固定索式屋顶摩天轮，针对摩天轮基础柱点的不均匀沉降，采用midas gen软件对其进行数值仿真分析，并通过现场测量结果与仿真结果进行对比分析，结果验证了仿真所得数值模型的合理与可靠，解决了因基础柱点不均匀沉降给摩天轮固定索带来内应力的问题，揭示了不对称布置拉索的竖向拉力与沉降之间的影响关系，提出了解决不均匀沉降对摩天轮钢结构影响的方法，为宁波等地区与商业综合体结合的摩天轮设计提供有益参考。

Abstract:

In recent years, the number of rooftop ferris wheels integrated with commercial complexes has increased. Therefore, the analysis of the interaction between the ferris wheel and commercial complexes has become more important. The fixed-cable roof ferris wheel is mainly studied. Aiming at the uneven settlement of the ferris wheel foundation column points, the midas gen software is used to carry out the numerical simulation analysis on it, and the field measurement results are compared and analyzed with the simulation results. The results verify the rationality and reliability of the numerical model obtained from the simulation. The problem of internal stress caused by the uneven settlement of the foundation column points to the fixed cable of ferris wheel is solved. The relationship between the vertical tension and settlement of asymmetrically arranged cables is revealed. A method to solve the influence of uneven settlement on the steel structure of the ferris wheel is proposed, which provide a useful reference for the design of the ferris wheel integrated with commercial complexes in Ningbo and other areas.
