摘　　要：抱杆腰环拉线的布置方案对特高压输电铁塔组立施工的效率和安全性具有重要影响。为研究得到经济合理、安全可靠的抱杆腰环拉线布置方案,根据GGTY2×7 t/16-1000型落地电动旋转双平臂抱杆的真实尺寸,运用有限元分析方法,建立了特高压输电铁塔组立工况下的抱杆-腰环-拉线耦合力学分析模型,计算得到了不同工况、不同典型腰环拉线布置方案时抱杆和拉线的力学特性,通过对抱杆位移和拉线张力的分析,得到了最优的抱杆腰环拉线布置方案。研究得到的抱杆-腰环-拉线耦合计算方法和分析结论可为特高压输电铁塔组立提供技术支撑,提升施工组立的效率与安全性。The layout scheme of guyed pole waist ring cable has an important influence on the efficiency and safety of UHV transmission tower erection construction.In order to study and obtain an economical,reasonable,safe and reliable layout scheme of holding pole waist ring cable,according to the real size of GGTY2×7t/16-1000 type landing electric rotating double flat arm holding pole,this paper uses the finite element analysis method to establish the holding pole-waist ring-cable coupling mechanical analysis model under the condition of UHV transmission tower assembly.The mechanical characteristics of holding pole and cable under different working conditions and different typical waist ring cable layout schemes are calculated.Through the analysis of the displacement of holding pole and the tension of cable,the optimal arrangement scheme of holding pole waist ring cable is obtained.The coupling calculation method and analysis conclusion of pole-waist-strut coupling obtained in this paper can provide technical support for UHV transmission tower assembly and improve the efficiency and safety of construction assembly.
