正射影像航测在山区电力线路设计中的应用

Application of Orthophoto Image Aerial Survey in the Design of Upland Power Lines

与常规测量方法相比,航测具有直观、效率高、劳动强度小、便于三维设计等优点,在220 kV及以上架空线路中应用普遍,而在110 kV及以下架空线路中应用不多。以某山区线路工程为例,分析了正射影像航测在110 kV及以下线路工程中的应用效果,为此类电压等级线路工程设计提供一种新思路。

Compared with conventional measurement methods,aerial survey has the advantages of intuitiveness,high efficiency,low labor intensity and easy to carry out 3D design,which is widely applied in 220 kV and above overhead lines,whereas rarely applied in 110 kV and below overhead lines.Taking the power line project implemented in an upland area as an example,the application of orthophoto aerial survey in the engineering of 110 kV and below power lines is analyzed,which offers a new design idea for the engineering design of such 110 kV and below power lines.
