“…In recent years, in the aspect of mechanical simulation of pole towers, many scholars have systematically studied the destruction mechanism [2][3] of power transmission towers under ice load and wind load based on the finite element model of steel mechanism beam unit, but rarely studied the mechanical characteristics of pole towers under foundation settlement condition. In terms of real-time monitoring of tower attitude, the existing online monitoring methods include tower tilt angle monitoring based on inclination sensor [4], tower deformation monitoring based on satellite differential positioning technology [5], and tower structure strain monitoring based on strain sensor [6], etc. The existing monitoring methods can assist the traditional manual inspection.…”

the rainstorm erosion, soil erosion and other factors will cause the settlement or unbalanced changes of the tower foundation, which will seriously affect the safety of the transmission line operation. This paper takes a 220kV dangerous tower under foundation settlement as the research object, establishes the finite element model of fine tower and foundation, simulates the stress distribution of each part of the tower under the actual foundation settlement condition, and determines the weakest node of the tower and install a monitoring system. Based on the finite element simulation results under various operating conditions, the reliability of the simulation results is obtained, and the early warning is given according to the real-time monitoring results of the system. In addition, the study can guide the stability of poles and towers under foundation settlement conditions.
