Abstract
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.
