Investigation on numerical model of electrical transmission tower-line system with a big span

大跨越输电塔-线体系数值分析模型的研究

The evaluation of dynamic characters of electrical transmission tower-line system with a big span is a key step for its wind resistant and seismic resistant design.

大跨越输电塔-线体系的动力特征评估是其抗风、抗震设计的重要环节。

With a height of 257 m, the long span crossing tower over mountain Ma'an of the 500 kV Chuma line of East China Power Grid is the highest steel pipe tower being constructed in China.

华东电网500kV滁马线马鞍山大跨越塔高257m，是目前国内在建的最高的钢管塔。

By introducing the concept of longitudinal stiffness of the bridge tower make the improved virtual beam method used in the analysis of multi-span suspension bridge.

通过引入桥塔纵向刚度的概念，把改进的虚拟梁法应用于连跨多主跨悬索桥的求解中。

The ultra-high voltage ( UHV) transmission line is more susceptible to the hazards of the ice storm because it has the features of long routes, passing through the areas with heavily ice covered, large span between the tower and mostly using of splitting wires.

超高压线路由于具有线路长、穿越覆冰严重的地区、铁塔之间的档距大和多采用分裂导线等特点，更容易受到冰灾的危害。
