Abstract

In the design of 500kV ultra-high voltage transmission towers in mountainous areas, the choice of tower slope will affect the size of the tower's root opening, thereby affecting the applicability of the tower in mountainous areas. At the same time, the choice of tower slope will also cause the tower weight and foundation force to be generated. Differences, thereby affecting the construction cost of the project. Combining actual engineering, taking a 20mm ice zone 53ZBC33 tower type for a 500kV line project as an example, a total of 8 different slopes of 0.09~0.16 for transmission towers of 60m, 54m, 48m, and 42m are calculated. The tower is used as an example. Steel quantity cost, foundation cost, and tower foundation land compensation fee are used as indicators to compare and analyze the project cost. When the calling height of the transmission tower is different, the corresponding economic slope is slightly different, but the overall economic slope fluctuates in the range of 0.10~0.13. In the actual design process, the economic slope of the tower can be quickly calculated in the slope range of 0.10~0.13.

500kV超高压输电塔的计算机建模与计算研究

在山区500kV特高压输电塔的设计中，塔坡的选择会影响塔根开度的大小，从而影响塔在山区的适用性。同时，塔坡的选择也会引起塔自重和基础力的产生。差异，从而影响工程的施工成本。结合工程实际，以500kV线路工程20mm冰区53ZBC33型塔型为例，对60m、54m、48m、42m输电塔共计算了0.09~0.16的8种不同坡度。以这座塔为例。以钢量成本、基础成本、塔基础土地补偿费为指标，对工程成本进行比较分析。当输电塔呼叫高度不同时，相应的经济斜率略有不同，但整体经济斜率在0.10~0.13范围内波动。在实际设计过程中，可以在0.10~0.13的坡度范围内快速计算出塔的经济坡度。
