输电线路牦牛造型景观塔设计与优化研究

Design and Optimization of Transmission Line Yak Landscape Tower

针对目前景观塔结构设计缺乏统一的原则和标准,造型设计突破性不强,塔重指标偏重和经济性欠佳的问题,以藏区牦牛造型景观塔为例,分析总结了景观融合思路、造型深化设计步骤和方法,以及结构布置和节点优化方法,为后续景观塔设计提供思路。重点对牦牛造型景观塔的结构布置方案进行了介绍;结合真型试验数据,基于虚功原理,对酒杯塔曲臂K节点的变形进行了分析,并在此基础上提出一种新的曲臂结构;基于有限元分析结果,优化了曲臂K节点构造。提出的一种新的曲臂结构,K节点相对变形小,避免了瓶口节点正侧面受力不均,有利于提高结构的安全可靠性。

Given that there is lack of unified principles and standards,weak breakthrough in appearance design,and poor economic efficiency for landscape tower,taking the Tibetan yak landscape tower as an example,the landscape integration ideas and summarized,deepening design steps and methods,as well as structural layout and joint construction optimization methods were analyzed,providing ideas for subsequent landscape tower design.The structural layout scheme of yak landscape tower was mainly introduced.The deformation reasons for K-joint of curved arm were analyzed based on the actual test data,and a new type of curved arm structure was proposed.Based on the results of finite element analysis,and the K-joint structure of curved arm was optimized.The new type of curved arm structure,whose K-jont has relatively small deformation,and can avoid uneven force distribution on the front and side of the slope changing joint,which is conducive to improve the safety and reliability of the structure.
