The ground subsidence of a power supply station leads to wall cracking,which seriously affects the safe operation of the power supply station.In order to identify the inducing factors of ground subsidence and settlement.Based on geological survey,the high-density resistivity method with high resolution,fast and accurate,and obvious abnormal response characteristics is selected as the non-destructive testing method,and applied to foundation settlement detection in this paper.Through inversion processing of conventional high-density electrical method and ultra-deep high-density electrical method,combined with forward simulation and comparative analysis.Through the inversion processing of conventional high-density electrical method and ultra-deep high-density electrical method combined with forward simulation,the results show that the high-density electrical method effectively delineates the weak interlayer at the bottom of the power supply station,and the validity of the geophysical interpretation results is further verified by drilling,which provides a basis for the induced factors of the power supply station subsidence.
