One of the most important methods of soil compaction is dynamic compaction, which is one of the oldest and economical methods of soil improvement up to great depths. This method is applied due to its many benefits, including its economic procedure to correct many kinds of soil. One of the most important issues that affect soil improvement methods is being economic. The three main methods of using piles, chemical modification, use of Menard density and vibrating tools are used for soil compaction at the time of presentation of an improvement project. The Menard method due to its much lower cost is more widely used than other methods. Considering the importance of the economy factor in the country's development projects, the need for 3D simulation and the ability of ABAQUS software to deliver the results of this research to a numerical model that can be used in civil engineering projects is becoming more important. The purpose of this paper was to evaluate the numerical modeling of dynamic compaction using finite element method and using ABAQUS software to improve the foundation by changing to height and weight of the compactor through Menard method for three cities of Ahvaz, Abadan, and Mahshahr. The results showed that the increase in the height of the fall resulted in an increase in the depth of the impact for all three categories with different weights of compactor. In addition, the depth difference was less affected in the high weights, which shows that the only weight increase of the compactor cannot be a factor in increasing the effect of soil compaction.
