摘　　要：以某地区220 kV某线路技改工程为例,引入无人机激光雷达系统对现场展开勘测,结合三维数据模型,实现对施工关键点的多维度测量、定量分析和方法验证,并成功拆除了跨越铁路的线路。通过人工勘测与无人机激光雷达系统勘测两种方式的优缺点分析,说明在条件复杂的架空线路改造中,结合无人机激光雷达系统勘测方式,更有助于摸清地形地势,测得全面而准确的数据,制定出最优施工方案。Taking a 220 kV transmission line upgrading project as an example,a UAV LiDAR system is introduced to onsite survey,which based on a three-dimensional data model,leads to the realization of multidimensional measurement,quantitative analysis and method verification of key construction points,and the successful demolishment of a segment of an old railway-overcrossing transmission line.Through the comparative pros and cons analysis on manual and UAV LiDAR surveys,it shows that in the upgrading of overhead transmission lines under the complex conditions,a UAV LiDAR system introduced in survey is more helpful in getting a clear picture of terrain,the acquisition of comprehensive and accurate data,and formulation of the optimal construction scheme.
