Transmission lines cover a wide range

and have long transmission distances

bad environmental conditions and complex geological terrain

so there are many problems such as low efficiency of inspection

long cycle of re-inspection

inaccurate monitoring data and so on. In view of a 220 kV transmission line

there are tower foundation settlement caused by geological disturbance

the deformation of main materials and the increase of inclination of the tower. The Beidou navigation system and the foundation reinforcement system are used to accurately and reliably obtain high-precision monitoring data of millimetre level and comprehensively grasp the real-time status information of various risks. Through constructing the disaster prevention monitoring system for tower deformation and geological hazards of tower foundation in transmission lines

the field application and data analysis provide a technical reference for the application of line disaster prevention.
