Abstarct: Due to the rapid increase in population and the ever-increasing expansion of urbanization, as well as the limitation of space, the need to build buildings and structures that can accommodate a large population is felt. Therefore, we come across structures that are particularly sensitive and of course must have sufficient stability. One of the effective parameters in the stability of the structure is its bed soil. Since the entire structure is mounted on the subsoil, its stability and strength are of particular importance. Therefore, before building the structure, the subsoil must be completely strengthened. One of the most common and effective methods in soil improvement is dynamic compaction. In this method, using a pre-designed pattern, a heavy hammer is thrown from a certain height on the soil surface and compacts the soil. The current research is baxsed on software calculations with the help of finite element numerical solution method and using Abaqus software. After referring to a reference article and checking the correctness of modeling and software performance, numerical modeling and checking the performance of soil and ram after the fall of ram will be done. The parameters studied in this research are the effect of different hammers on the amount of settlement of different soils after each impact and in different arrangements. According to the results of the modeling done, the 25-ton drum with a fall height of 15 meters in a square arrangement and in only 2 executions provides a suitable performance.
