In this study we investigated a circular foundation with experimental method and drawn its loadsettlementcurve. Then we numerically have modeled it using Plaxis software. After calibrationobtained curve from numerical calculation with the laboratory test's curve, we had investigated theeffect of geo-grid, retaining wall, water in foundation and changes in E, Ψ,C by load-settlement curve.
