在进行带电跨越施工时，选择合适的方式很关键。围绕着带电跨越方式选择这一核心问题，对层次分析法中1—9标度法、10/10—18/2标度法和9/9—9/1标度法这3种标度法进行比较，计算结果表明10/10—18/2标度法较优。基于改进的层次分析法，构造了选择带电跨越方式的层次分析结构模型，并以某条线路施工为例，对3种带电跨越方式进行综合评估和计算，计算结果表明，该条线路施工中最优的带电跨越方式为索道跨越。

It is crucial to choose the appropriate way in live-wire crossing construction. Closely centered on the issue of live-wire crossing method selection, three scale methods of 1-9, 10/10-18/2 and 9/9-9/1 in analytic hierarchy process (AHP) are compared, whose results showed that the scale method of 10/10-18/2 is better. Based on the improved AHP, the hierarchy model for live-wire crossing method was constructed. Finally, three live-wire crossing methods were comprehensive evaluated and calculated by taking a power transmission line construction as an example, which showed that the cableway crossing is the best.
