In order to study the stability parameters of Yingshang 110 kV Substation landslide under heavy rain conditions,this paper uses Midas GTS/NX software to establish a three-dimensional slope model of Yingshang Substation.Based on systematic analysis of the geological background of the Yingshang Substation landslide area,the influencing factors of the landslide,the basic conditions of the landslide,and the stability characteristics of the landslide,the engineering support measures for the landslide management of Yingshang Substation are proposed.This paper optimally designs the support parameters of the landslide in Yingshang are optimized,and the final support parameters were also demonstrated in engineering.
