摘　　要：合理选择牵张场可保证张力架线的顺利进行,有效提高张力架线施工效率,实现张力架线经济效益指标,是输电线路工程架线工序中的一项十分重要的工作。大修技改项目作为输电线路的其中一段,牵张场选择局限性大,可调性小,因此显得更加重要。牵张同场以旧牵新施工方法将牵张场设计在一处,对传统的张力架线牵张场设计在两处的施工方法进行了大胆创新,在750 kV拉官线64号塔地质滑坡改造工程得到了成功应用,为今后同类工程施工提供了重要参考和指导。Reasonable selection of stretch field can ensure the smooth progress of tension wiring,effectively improve the construction efficiency of tension wiring,and achieve the economic benefit index of tension wiring,which is a very important work in the wiring process of transmission line engineering.As one of the sections of the transmission line,the overhauling project is more important because the selection of stretch field is limited and the adjustability is small.The old and new construction method is used to design the stretch field in one place,and the construction method of the traditional stretch field design in two places is boldly innovated.It has been successfully applied in the geological landslide reconstruction project of Tower 64 of the 750 kV Laguan Line,which provides an important reference and guidance for the construction of similar projects in the future.
