Description
Summary:Impact rollers are used in different parts of the world such as Australia and South Africa to improve soil properties. Due to the high depth impact of this roller compared with vibratory rollers, this type of roller is used in dam construction to compress and reduce the permeability of soil and create an impermeable layer, reduced water losses. Given the importance of constructing embankment dams, using this technology can be an effective to increase storage efficiency. In this study, numerical analysis of density rate was done using a trihedral impact roller. ABAQUS software in a two-dimensional mode and the plane strain were selected as the proper model due to responses closer to the experimental results. The results showed that the distribution of cavity pressure at the impact area of the roller has many changes, and these changes reduce in the soil depth, reaching to an almost constant rate.
