摘要

为研究拉线初张力对±800kV特高压双柱悬索拉线塔抗风性能产生的影响，分别取拉线初张力为其设计承载力的15%、20%、25%，进行了塔线体系气动弹性模型的风洞试验。试验结果表明：拉线初张力的改变对荷载状态下塔线体系的受力性能影响显著，且对双柱支座反力和拉线拉力的影响呈非线性关系，应对拉线初张力进行优化选取。

Abstract

The effect of guy initial tension on wind-resistant performance of the ±800kV direct current (DC) cross-rope suspension tower-line is investigated through an aero-elastic model test in a boundary layer wind tunnel. Three kinds of guy initial tensions (15%, 20%, and 25% of the ultimate stress) were selected. The results show that the changes of guy initial tension have a significant influence on mechanical properties of tower-line system under wind load condition. There is a nonlinear-relationship influence on tension in guys and compression in masts. Thus the guy initial tension should be selected optimally.
