摘要
利用非线性有限元软件TOWER建立V型拉线塔的结构计算模型,以减轻塔重为目标,从挂线方式、塔头型式、拉线设置方案及主柱截面几个方面进行优化分析,并与自立式铁塔进行技术经济比较。结果表明V型拉线塔进行优化设计后可取得显著的经济效果,其优化措施可为今后相关工程的V型拉线塔设计提供参考。
A calculation model of V-type guyed tower was established by nonlinear finite element software tower. In order to reduce the tower weight, optimization analysis was carried out from aspects of conductor hanging way, tower head type, cable setting scheme and main column section, as well as the tower＇s technology and economy were compared with those of self-standing tower. The results showed that the optimal design of V-type guyed tower could achieve significant economic effect, and its optimization measures could provide references for V-type guyed tower design in relevant projects in the future.
