特高压输电线路典型索道运输方案经济性研究

Economic Study on Typical Cableway Transportation Scheme for UHV Transmission Line

对索道运输方案的设计内容及费用组成进行分析,梳理索道运输的主要影响因子,从而建立索道运输典型方案模型。针对特高压输电线路运距及运量特点,依托索道运输典型方案模型,通过对各种地形条件下不同索道运输方案及人力运输方案进行费用测算比较,得到相应索道运距下的临界人力运距。研究思路同样适用于其他不同电压等级输电线路相应平均档距及运量的工程前期索道运输方案设计。

The design contents and cost compositions of the cableway transportation scheme are analyzed,and the main influencing factors of cableway transportation are sorted out , then a typical model of cableway transportation scheme is established.According to the characteristics of transportation distances and freight volumes of UHV transmission line,the critical manpower transportation distances under the corresponding cableway transportation distances are obtained by calculating and comparing the costs of different cableway transportation scheme and manpower transportation scheme under various terrain conditions relying on the typical cableway transportation scheme model.The research approach is also applicable to the design of cableway transportation scheme in the early stage of other transmission line at different voltage levels with corresponding average spans and freight volumes.
