摘要
本文分析了铅垂测量法、经纬仪测量法、平面镜测量法及地面三维激光测量法测量线路杆塔倾斜的原理及特点。现场实测结果表明铅垂测量法需要工作人员登塔作业,存在作业量大和风险高、效率低的不足;经纬仪测量方法虽无需登塔,但对测量地理环境要求高且操作繁琐、测量精度不高;平面镜测量法也不需登高作业,不受地形限制但操作复杂,精度较低;地面三维激光测量法具有非接触测量、便携、精度高、形象直观等优点,测量结果便于存档和追索,值得推广应用。
The principles and characteristics of several transmission line tower inclination measurements are analyzed in this paper,including plumb measurement,theodolite instrument measurement,plane mirror measurement and TLS measurement.Field test results show that the plumb measurement requires tower climbing,which results in much workload,high risk and ineffectiveness.Tower climbing is unnecessary for theodolite instrument measurement,but strict environmental condition is required,with complex operation and low precision.The plane mirror measurement requires no climbing operation and geographical restrictions,but still with complex operation and low precision.The 3D terrestrial laser scans measurement possess the advantages of non-contact characteristic,portability,high precision and visualization,easy archiving and sourcing,which should be widely applied.
