覆冰荷载下塔线体系的力学性能分析

Tower line system under ice load analysis of the mechanical properties

介绍建立了一个耐张段内三塔四线体系的有限元模型,通过改变重力加速度来施加荷载的方式,分析了在各种荷载共同作用下塔线体系的力学性能。结果表明,相对于导地线自重来说,覆冰荷载对输电塔所起的作用越来越大,塔线体系相对于单输电塔更容易受到破坏。

This paper established a tension within the period of fnite element model of three towers four wire system, through the way of change the gravity acceleration to load, is analyzed under various load combination tower line system mechanics performance.The results show that the relative to ground wire guide self-respect, the role of ice load on the transmission tower is more and more big, the tower line system relative to the single transmission tower is more vulnerable to damage.
