Obtaining bearing capacity of the footing is among the factors influencing the footings design. In this paper, the study of the type and depth impact of the soil granulation above the bearing capacity of the ring footing through the assistance of FLAC software is conducted. The failure criterion intended for the soil is Mohr-Coulomb. The study of the bearing capacity of ring footing of ten thousand cubic meter of Mazut tank of Mashhad Cement Company on three types of soil, topsoil, clay and sand has been carried out. The results indicate that the loading capacity increases by granularity becoming coarser due to the increase of the contact area of the granulation and the increase of friction and the soil structure stability. Also the less the poorer soil depth (in terms of granularity) is, the more limited subsidence is, hence the bearing capacity increases.
