Abstract :
    The application of rock columns is known as an effective method for soil remediation and is used in loose sandy and clay soils. In soft soils, the main reason is the failure of the boulder rock pillar, which is generally aimed at increasing rock bearing capacity, and reducing bearing capacity. Soil is habitable. In the present study, geogrid ammunition was added to the stone column in vertical or horizontal combination with vertical spacing of dc0.5 and dc0.25 and tried to improve rock column behavior with different armor arrangements. The time has come. By comparing different methods of armament The rock column meeting and comparison of the amount of geogrid applied to the rock column have provided optimal arming arrangements. The reinforced stone columns have been modeled and analyzed in Plaxis 2D software using the above methods, finite element method. The results showed that the bearing capacity increased, the subsidence decreased, and the bending of the reinforced rock columns combined.
