摘　　要：基础作为输电线路的重要组成部分,基础方案的制订及实施对于工程造价、建设周期、劳动安全及环保要求具有重要影响。在山地、丘陵地带,机械化施工线路基础一直是个难题,文章结合某特高压交流线路工程(湖北段)山丘地区48基挖孔桩机械化施工,与常规人工挖孔桩施工进行技术及经济对比,旨在为山丘地区特高压线路挖孔桩机械化施工的推广应用提供借鉴。The foundation is an important part of the transmission line,and the formulation and implementation of the foundation plan has an important influence on the engineering cost,construction period,labor safety and environmental protection requirements.In mountainous and hilly areas,mechanized construction of line foundation has always been a difficult problem.This paper combines 48 foundation digging pile mechanized construction in mountainous and hilly areas in a UHV AC line project(Hubei section)to conduct technical and economic comparison with conventional manual digging pile construction,aiming to provide reference for the promotion and application of digging pile mechanized construction in UHV transmission lines in mountainous and hilly areas.
