Abstract
In this study, we tried to confirm the influence range in the ground due to Bulbed, Reinforcement change and ground conditions change through numerical analysis. By checking the increase width of the reinforcement effect accompanying the increase of Bulbed, grasping the trend accompanying the change of the ground conditions and deciding soil nail Reinforcement and Bulbed, so that economical construction will be carried out It can be judged that it can be utilized as basic material. In this paper, we analyzed the Displacement due to positional load of reinforcement by utilizing MIDAS GTS NX which is a universal numerical analysis program. In addition, it is necessary to ensure the diameter star economy of Bulbed size and Reinforcement by comparing / analyzing whether the Bulbed relaxation region of Reinforcement represents arbitrary characteristics in the ground in Sandy soil, Weathered granite soil ground due to soil nail pullout load Numerical analysis was conducted to select criteria that can be done.
