Abstract: In order to meet the need of temporary stability and urgency of rescue project of excavation landslide, a simplified method is proposed for micropile design on the basis of the analysis of the role and the existing researches on micropiles. The approach is applied to the design in rescue project of excavation landslide in Hengyang, and the finite element simulation is carried out by using two-dimensional geotechnical analysis software Soilworks to verify the feasibility of the program. Three displacement monitoring points are arranged to monitor the treatment program for two months in the field. The treatment effect of field monitoring feedback shows that the proposed simplified method for steel micropiles is feasible. It is simple and practical, and it has good reference and guidance for the design other similar rescue projects.
