摘　　要：在三沪±500 kV直流输电线路铁塔规划过程中,分析了线路地形气象条件,以线路实际优化排位的统计数据作为基本依据,同时参考了地形条件极为相似的龙政线、葛南线的设计经验,经多方案比较后规划出了科学合理和适合工程实际情况的杆塔系列。该系列铁塔的水平、垂直档距组合分级合理,水平档距利用率较高,并根据地形情况,既规划了适合山地的全方位高低腿塔型,又规划了适合平原地区的平腿塔,还有适合林区和房屋密集地区的"V"型串塔,有效地降低工程造价,并保护了自然环境。During tower planning process of Three Gorges-Shanghai ±500 kV DC transmission line, through analyzing terrain and weather conditions along the line, and on the basis of statistic data of optimized arrangements, in the mean time, utilizing design experiences from Long-Zheng and Ge-Nan Lines that have similar terrain conditions, pole and tower series that are rational and suitable for engineering practices are selected after comparison of multiple plans. The combinations of horizontal and vertical spans are rationally graded, and horizontal spans have higher utilization. Based on terrain conditions, both adjustable-legged towers suitable for mountain area uses and even-legged towers suitable for plain uses are selected, besides, V-shaped string towers suitable for forest and dense building areas are also selected to reduce construction cost and protect environment.
