| 摘 要： | 对110kV单回路输电线路铁塔进行结构设计时,为了弄清楚断线工况对铁塔重量的影响程度以及断线工况所控制的杆件位置及类型,首次计算并未考虑断线工况对铁塔的影响,并得到了满应力计算结果。第二次计算时,通过追加断线工况荷载,验算了首次满应力计算结果,并得到了断线工况所控制的杆件位置及类型。对比两次计算最终结果,得到了断线工况对铁塔重量的影响程度。

| Abstract: | While doing structure design to 110kV single-circuit transmission tower, in order to make clear how broken wire conditions effect the tower weight and find out controlled rods position and type by broken wire conditions, we don＇t consider the influence of broken wire conditions to tower weight for the first calculating and obtain full stress calculation results. When beginning compute for the second time, we add broken wire load, check full stress calculation results of the first calculating, and get controlled rods position and type by broken wire conditions. Contrast twice calculating results, we know that how broken wire conditions effect the tower weight. |
