In this study, the comparison and examination of the settlement of domestic waste landfill by improving the foundation through Dynamic Compaction Method, Chemical Grouting Method, and Cement Grouting Method for reuse of domestic landfill. Plus, an estimation of modulus of elasticity of waste landfill has been done through Plate Bearing Test. The fact that soil from the landfill site has little organic content and high permeability reveals that the settlement by decomposition as well as that by consolidation is neglectable, but, olny an elastic settlement is expected to occur. It turned out that there was much difference among the predicted values estimated by each theoretical formula for the elastic settlement. An estimated settlement by Osterberg formula was best fit to that by numerical analysis.
